[Solved] Problems with attaching images and editing posts in Firefox
The forums work great in Chromium-based browsers such as Chrome, Edge, etc. However, Firefox is having issues with attaching images and editing posts.
Please note that I have let the edit window load for several minutes and it never stops loading.
Using Firefox 104.0.2 (the latest as of this post).
I've just discovered that Firefox won't delete posts either.
Please also note that I have cleared all server caches, Cloudflare cache, wpForo caches and my own browser caches. I've also instructed my users to clear their browser caches, delete the cookies associated with my site, re-login, and try again. They are still having the same problems.
Also, a couple users are now reporting that the same problems exist in Chrome. I have not been able to replicate the issues in Chromium-based browsers, but the problems do remain in Firefox.
There is a long thread on my forum about this: https://surveyorconnect.com/community/support-bug-reports/much-weirdness-around-editing-posts/
This seems related to the addon for wpForo. I just tested it at a client site and seems to work just fine (WP 6 and wpForo 2.0.7 and PHP 8).
But could be also related to this issue you have (and should fix) ?
