I found out that when a thread is closed for comments (using the native WordPress setting, see screenshot), editing any already published comment doesn't work. This is what happens:
Close the comments section
Edit a comment from the frontend:
The console shows this error:
And there's no way to edit the comment. Stays loading and shows a white box
We've tried disabling all plugins and it looks like it doesn't make a difference. Any idea what's happening? Let us know if you need any further info.
Thanks for reporting this issue in detail! This sounds like a frustrating blocker for your client. The fact that it happens specifically when comments are closed via WordPress's native setting is a key clue. When WordPress closes comments on a thread, it typically prevents new comments but should still allow comment authors to edit their own existing comments—so this behavior definitely seems like a bug.
Since you've already confirmed it's not a plugin conflict (by disabling all plugins), here are a few things worth investigating:
Check if there's a capability/permissions issue—make sure the user role has the edit_comment capability assigned
Look at your WordPress version and the plugin version you're using. Sometimes there are known compatibility issues between specific versions
Check if there are any custom code snippets or functions in your theme's functions.php that might be intercepting comment editing
Try temporarily switching to a default WordPress theme (like Twenty Twenty-Three) to rule out theme-specific conflicts
The white box and loading state suggests the AJAX request is failing silently. I'd recommend checking your browser's Network tab (in DevTools) when attempting to edit—that might reveal what the actual server response is. Also, check your WordPress error logs (usually in /wp-content/debug.log) to see if there are any PHP errors being logged during the edit attempt.
Have you had a chance to check the server-side error logs yet, or would you like guidance on how to enable WordPress debugging?
