I just updated our forum to the latest version of discourse. After the update, a white square box appears in the middle of the forum and prevents any action. You can’t click on just anything.
Thanks Gerhard,
It actually works in safe mode. But how do I troubleshoot to know which plugin is causing the problem? My co-founder installed some plugins some time ago, but he decided to part ways a few weeks ago.
This is likely caused by discourse-content-locker which has been in broken status for over two years now. You might want to try the guest-gate plugin which has been forked from the content-locker plugin.
