Our forum, which is hosted by Discourse, is suddenly gone - it doesn’t show any posts anymore and there’s a big JS error in the console.
Any idea what might be the issue? I was thinking it could be an issue with the theme, but I’ve checked and it’s fine as far as I can see (We still have access to the admin panel)
We reverted the change via this commit. Thanks @hithere for identifying the precise issue!
As an immediate workaround, Safe Mode should allow you to access the affected forums. That will temporarily disable any themes/plugins which are triggering the deprecation notices.
We’ll get this fix rolled out to our hosting ASAP - very likely within the next hour.
