This forum is filled with outdated responses, but I will try to get an answer anyway.
I received an email from WordPress that says:
“Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email. In this case, WordPress caught an error with one of your plugins, BuddyPress to WordPress Full Sync.
Everything on my server-side is updated.
WordPress version 5.9.3
Current theme: Cera (version 1.1.13)
BuddyPress 10.2.0.
BuddyPress to WordPress Full Sync (version 0.3.7)
PHP version 7.4.28
I deactivated, then subsequently deleted BuddyPress to WordPress Full Sync. I then downloaded a clean copy of the plugin from the WordPress plugins page. I re-installed and re-activated it without difficulty.
I still cannot upload the group profile picture. I can upload the group cover image, but not the profile picture. The image uploads but fails at the cropping stage. I have read the other responses. My file name was never long, but even the file name “g1” does not work, so the filename length does not seem to be the issue. I have tried different sizes and extensions (.png and .jpeg) with consistent failure.
