Why won't my theme editor load on the admin page?

[Forever-Curls]

I haven't been able to load my theme editor for the past few hours. It was acting very slow and will not load at all now. My internet is fine. The admin page loads in a quick manner, but when I click on the customize button it never finishes loading the theme editor.

Hi, @Forever-Curls! 

This is Rae from Shopify. I'm happy to help out with this! 

Which browser are you using currently? I recommend ensuring it's one of our supported browsers, and then clearing the cache before trying to access the theme editor again. 

If that doesn't help resolve things though, please also give these steps a try when opening up your theme editor: 

• Using another device - like a mobile device, or another computer. 
• Using a Chrome Incognito window. 
• Resetting your internet connection, or using a different internet connection altogether. 

Can you also please confirm which theme you're using? Does this same issue happen when you try to customize other themes in your admin? To test this out, just follow these steps:

1. Log in to your Shopify admin
2. Click on 'Online store > Themes' 
3. Scroll down to 'Theme library' and click 'Customize' beside one of your themes listed here. 

If you don't have any other themes in your theme library, you can download a free theme to test this on. To try this out, head back into the 'Online store > Themes' section of your admin, click on 'Explore free themes', click on 'Debut', and then click 'Add to theme library'. Once Debut has downloaded to your theme library, you can follow the steps above to try to open the theme editor on this theme. 

Please keep me posted on how this all goes. I look forward to hearing back from you with an update!

[MICHAEL7318]

same thing over here. must be a problem on the shopify side

[K_L]

I'm also having the exact same issue and again tried all of the above methods to get it to work and on safari & chrome across 3 devices...! Really hoping this is a momentary glitch as I don't want to lose all my work.

[MICHAEL7318]

i just refreshed again and its working now

[jsaylors235]

yeah same here!

Hi, everyone! 

I appreciate you all joining this thread to discuss the troubles you were experiencing. 

We did have a brief interruption on June 18, 2021 that impacted the theme editor, and how it loaded on Shopify's end. However, this was quickly resolved, and you should all now be able to access the theme editor correctly. 

If anyone is still running into issues with this though, please let me know and I'll be happy to continue helping out. 

Thanks, 

[zacharytipton]

Rae, I am having the same issue. the theme editor page is not loading. 

[Rae]

Hi, @zacharytipton! 

Thanks for letting me know.

Did you have a chance to try out some of the troubleshooting steps I previously shared in this thread? You can find these here: 

• Using another device - like a mobile device, or another computer. 
• Using a Chrome Incognito window. 
• Resetting your internet connection, or using a different internet connection altogether. 

Equally, does this same issue happen on all of the themes within your theme library, or just with one particular theme? You can follow these steps to test this out: 

1. Log in to your Shopify admin
2. Click on 'Online store > Themes' 
3. Scroll down to 'Theme library' and click 'Customize' beside one of your themes listed here.

If you don't have any other themes in your theme library, you can download a free theme to test this on. To try this out, head back into the 'Online store > Themes' section of your admin, click on 'Explore free themes', click on 'Debut', and then click 'Add to theme library'. Once Debut has downloaded to your theme library, you can follow the steps above to try to open the theme editor on this theme. 

Let me know if these steps help resolve things for you! 

[zacharytipton]

thanks for getting back to me
It happens only on the published theme (lorenza)
I can load debut.

[Rae]

Hi, @zacharytipton! 

I appreciate these extra details. 

Since this issue is only happening with the Lorenza theme, it's possible that this problem may be tied to the theme specifically.

Lorenza is a third-party theme developed by Fluorescent Design Inc., so I recommend reaching out to them directly to confirm why this may be happening. You can contact these developers by viewing Lorenza in the Shopify Theme Store using this link, and then clicking 'Support' on the right hand side of the page. 

Please keep me posted on how this goes! 

[zacharytipton]

Rae,

I have tried another device

I have used a different internet connection

I have used debut theme (works)

I have used incognito. 

I still can not edit the lorenza theme. 

this is what I get:

Please help me fix this. 

Zack

[Rae]

Hi, @zacharytipton! 

Thank you for trying out those troubleshooting steps. 

Since the theme editor is loading correctly on Debut, and this issue is only occurring on the Lorenza theme, the best way to get this looked into further is to speak with your theme developers directly.

Did you have a chance to contact the Lorenza theme developers by following the steps I shared in my previous reply (linked here)? If not, please go ahead and follow those steps, as these developers are the best people to assist further with this. 

Best,

Mine has been doing this for over a week now. I am in the middle of Rebranding my store and I can't even edit my store theme because it won't load the theme page. I've tried deleting the cache and all but it's still not working. I can't even load any of the themes.

[Rae]

Hi, @LouLouNRooOwner! 

Thanks for joining this thread and letting me know. I'm sorry you're experiencing this issue during your re-brand, and I understand the importance of getting this resolved as soon as possible. 

To confirm, is it the theme editor specifically that's not loading? Or, are you unable to load the 'Online store > Themes' page in your Shopify admin?

Can you also please let me know the name of the theme you're using?

I'm happy to help further once I have these details! 

[Redroot_Blades]

hi @Rae , I'm having the same issue. Last night and today. 

Theme editor isn't loading. Cleared cache. Multiple browsers and devices. 

Won't load from Shopify app so it must be Shopify. 

Using Pipeline 2.0 theme. But nothing under the "Sales channels --> Online store". Will work. The menu will load, but all links give this error message: 

Thanks,

Dustin

[Jarno_vanhaute]

Hey i am having this issue for all themes and i have tried your suggested solutions. This issue is happening for debut as well as effortless 

[Focused4ever]

Hello Rae, it is now 2023 and I am having this very issue and there seems to really be no answer. But at the same time I see where Shopify Tech Support chimed in and said that they fixed the problem, but people still seemed to have issues after that as well. Nobody really says what to do if I am not having the issue when in incognito mode and it all loads just fine. Because that is what is happening with mine.  So what does that mean? That there is something wrong with my regular Chrome and I should contact them about it? Or is this still a shopify thing? Please let me know. Thanks

[ThirdCh]

Tried all of the above.  It's not working.

I can't even see any option load up, so as to change the theme compltely.

Heck, at this point, I would delete every bit of my work and start over if that would work, but if I dare to click on "Theme Library", then I can do nothing else.  Internet and the rest of my system is fine.  It simply will not load any option, any page.

Trying to edit blocks or individual pages is also pointless. NOTHING will load

[luxcarper]

it is not working bro!!! tried everything you said...

[Sune31]

Hi Rae!

I'm experiencing the same issue. I just installed a new theme, and the new (completely different theme)', s editor is also not loading. Any advice would be highly appreciated. 

[bes_projects]

Facing same issue from yesterday, My site is live but theme editor is not working. I have verified entire code and there is no issue with that.

[MichealVu]

I am facing the same problem. I am using defaulted theme of Shopify and I cannot edit although my Internet is fine, my Chrome is up to date and I have cleared cache. Please support me with this issue, thank you!

[dandiehl]

I am having the same issue as well. Cannot get the Theme Editor to load. Have tried using incognito window and same result.

[joycruz]

I got this issue here, followed solution above and didnt work

[mummetech]

For anyone experiencing this issue that has a modified theme, if you have custom coded blocks in the schema on a page/section, then added content to those blocks through the customizer, then later remove the blocks in the schema for that page/section, you will experience this issue.  You need to first go into the customizer and remove those blocks/content, then you can remove the blocks schema in the template.

[marchajj]

i am still facing this issue right now and replied on 3 threads: 

The Theme you're looking for couldn't be found

Check the web address and try again, or try navigating to the Theme Editor from Theme.  and my theme is arena commerce: https://support.arenacommerce.com/support/tickets/263394  and I faced an error:  and I am working on Firefox because am unable to work on normal browsing of Google Chrome i have an issue and reported CHROME SUPPORT and Shopify as well and hope soon it will be fixed but right now I am still facing this on firefox: https://prnt.sc/K9ExdYryXE6j any advice please would be much appreciated! this is really frustrating and so sad because I've been accessing the customer regularly and on a daily basis because this is my daily job work here and suddenly it stopped. i dont know what suddenly happened. can i create a new theme.liquid file from the other website? is this going to fix the problem now?  

but how come from the same browser I can open theme editor for KADOONPRO here: https://www.kadoonpro.com/ but not the case for KADOON PRO UAE: https://kadoonpro.ae/. I was working normally on it today morning and all the time before. What's happening here? I'm not sure if this is a Shopify issue because all other themes i have even the free one and demo i am able to customize easily. only the newsletter and the live theme ZEECO.

I cleared my cache and tried from Firefox and Chrome private browsing and facing this now: https://prnt.sc/TyTHVNOExE_n

[Alexmayberry]

Oh my god that worked. Thank you 🙂

[Baitbox]

Yes, this solved my problem! THANK YOU! ❤️

I had added some custom blocks to a .liquid file , then in the editor added an image and text to that block (which did not work they way I wanted ) so I just removed the code from the liquid file but not the changes I had made in the editor. 

adding the code back, meant i could load the editor, I then could remove the image and block in the editor which fixed the issue

[gina-gregory]

This can also happen if there's an error in your theme's config/settings_data.json file. If you know how to edit JSON, you could try duplicating your theme and then directly editing that code in the theme code editor. Start with a small value change somewhere, and then hit Save. You then might get an unrelated error message that could be the actual cause of theme editor issue. Based on the error message, try to resolve the issue and save. Once you validate that this fixes the issue, then make the same changes in your other theme.

[DavidField]

Turn off your anti virus program. This worked for me. Then figure out which part of the program is making you unable to edit it. 

[DavidField]

It actually was due to a browser extension.
