troymccann if you updated to Flarum beta 14, there's a conflict with fof/oauth
which will be fixed soon but isn't yet FriendsOfFlarum/oauth9
If Wordpress isn't redirecting, it could be a conflict with another Wordpress plugin. You could try temporarily disabling some Wordpress plugins to see if this solves the issue.
Same thing in Flarum. If it's not working, you can try disabling some extensions to see whether there's any conflict.
