When I am making changes to my Shopify theme in the custimizer I keep getting the message, "online store editor session can't be published", when I try to save it. I have had multiple users test it and it always seems to happen.
This is Luna from Shopify. I noticed you are new to our Community forum, welcome! Sorry to hear you've been dealing with this setback. I'm happy to help out.
To gather a little bit more context, what browser are you using? Is this happening on several devices? I recommend ensuring that you are using one of our support browsers. From there, you should clear your browser cache. After this, please try to close the browser completely and restart it before using your theme editor once again.
If that doesn't resolve the issue, please also try the following:
In the meantime, if this persists further I will ask that you try to customize another theme in your admin. Does the same error occur? To do so, please follow these steps:
If you don't currently have any other themes downloaded, please download a free theme for testing purposes. To do so, head back into the 'Online store > Themes' section of your admin, click on 'Explore free themes', click on any free theme, and then click 'Add to theme library'. Once this theme has been downloaded, please follow the steps listed above. Once you are finished, feel free to delete the theme from your library.
I'm looking forward to hearing how this goes for you. I appreciate your patience while we work to get this sorted out together.
Luna here. Were you able to resolve the error with those suggestions? If you are still facing any setbacks, please don't hesitate to let me know. We can continue to look into it together.
Thanks for getting back to me and completing the troubleshooting steps I provided above. I appreciate it! Based on what you've shared, it sounds like the issue is isolated to your theme's current version.
To gather a little bit more context, can you please let me know the following:
My understanding is that you've made some modifications to your theme's coding, is that right? If so, our next best step will be to find the route of this error based on the customizations that have been made. Please take a look at our help document: Troubleshooting.
As an alternative to reverting to an older theme, rolling back your current theme may be a better solution to resolve the issue. If you haven't made any customizations to the theme or recently downloaded any apps, please let me know.
Looking forward to hearing back from you, so that we can continue to work on this together.
Just checking in with you. Were you able to resolve this? If you have any questions or require additional assistance don't hesitate to reach back out.
I got the same problem. It is not because of the browser. One of our developer says that maybe because of the block limitation in Shopify. The other one has an idea that Shopify has limit of 250KB file size limit. We have tried to rolle back the them to almost 3 month a go but it is not working. It is really frustrating whn u want to develop your store and you get this limitation
The older theme in your case is worked because it seems that in older theme you did not add content, block and section to reach the limitation. If you try to add as much as content block and section like the live theme you will get the same error. Did you find any other solution for this problem?
@EliteScreens We did not find a solution to this and yes it seems to be some kind of limit to the blocks and sections.
I have found the problem and solution to that.
The problem is the limitation on the json file size in Shopify. So this means everytime that you write a code and this code combine some kind of content like links, SVG code, ect, this will add to the json file as well. So in time they sum up and take a space. Shopify put the hidden limit on the json file to max 1.5 MB. This means if you reach this limit, you are not be able to save any sassion any more because there is no more free space to use.
The solution is that:
1. delete all the hidden section that you do not need
2. with a developer delete all the blocks, codes, customized section, block and option that you do not need
3. try to use less SVG codes and custom CSS
these above solution have solved our problem, and we are now freely continue developing our shop. I hope that would help you too
