Error message when I attempt to customise theme

[Skittles]

Hello,

I have been building my store for the last few days but as of 1hour ago, I can no longer customise my theme. Anytime I try to do so, I get the following error message

I can access my shopify admin and other settings okay and my website is running well but I can no longer access theme editor.

My settings_data.json file was last updated 1 minute before my theme was last saved but I can not remember what I changed unfortunately.

If anyone could help me understand what is happening or how to fix, I would be much appreciative.

Thank you

Hi there @Skittles !

Thanks for sharing details and a screenshot of the issue you encountered with us here in the Shopify Community.

We did have an issue affecting some store admins earlier today, though that issue has since been resolved.

If you’re still coming across this error in your admin, try clearing the cache on your browser to ensure you’re viewing the live version of your store as it is online now.

Let me know if the issue persists for you still after clearing your cache, so we can check this out further!

You mentioned you’re working on building your store recently, is this a new store you’re working towards launching?

Can you tell me a bit about what you’re selling, and anything else you’re working on for your business?
