Version 2 has destroyed my forum, how doe I go back to version 1?
Destroyed? What exactly is the issue?
Can you post a url?
Restore your backup, i hope you have one.
If you cannot access to your dashboard, use some FTP client or the File Manager of your hosting cPanel and delete the /go2wpforo/ folder in /wp-content/plugins/ directory.
If there is no /go2wpforo/ folder then this could be caused by old Addons. Do you have old wpForo addons activated?
Please, first update all your addons to 3.0.0 version then update wpForo. All will work fine in this way. Also, please make sure you don't have an old Go2wpForo plugin installed, if so, just delete it.
I see that the disaster is the automatic-update, which is not intuitive. The automatic update should never do that if the version change is major. It should never update from 1.x.x to 2.x.x automatically, this is a big issue of WordPress core. On the other hand, you should never turn on the automatic update for large plugins like forum plugin or shop.
Everybody should use this:
