Some websites will display "Sorry Snippet could not be loaded"

[uubbbb]

I have several websites, some of which work perfectly fine with plugins, but some of which display a message "Sorry Snippet could not be loaded" when adding snippets, as shown in the picture. When clicking "published" or "delete", a message "File not found" appears, but the file does exist on the server. I'm sorry I can't reproduce this situation because I can't find any similarities or differences between these sites. It feels random to me. I hope I can solve this problem.

Can you open a support ticket here with a admin access so we can check and fix the issue.

Thank you for creating the ticket and providing access to your websites. I have tested and found that the issue stems from a conflict with another plugin named "Sync QCloud COS," which prevents the files created by FluentSnippets from rendering.

Please deactivate the conflicting plugins for a while and re-test the snippet on your end, as this resolves the issue. Furthermore, if you wish to continue using these plugins, you may contact the Sync QCloud COS support team for assistance.
