I keep getting this error and because of it I can't save changes made to Nodes.

Not sure if it's an xenforo issue or because I uninstalled this add-on + server files:

http://xenforo.com/community/resources/1-1-x-require-thread-prefixes.500/

@borbole and anyone else, thanks.

It is likely because you removed that add-on (which conflicted with XF). The author would be best positioned to know what it changed specifically, but you can run this query to re-add the column:

ALTER TABLE xf_forum ADD require_prefix TINYINT UNSIGNED NOT NULL DEFAULT '0';

I'm getting the exact same error! I also just deleted the required thread prefix aswell

@borbole It looks like this server error is definitely caused by your addon. Please investigate.
