I am not able to use any of the tools (such as like, solved, approve, delete, etc.) in a post, even as admin. However, if not logged in and I press the "Quote button, I get a popup that says Please Login or Register. The share button, RSS feed and profile buttons all work. All the other buttons and links outside the actual post work. I can reply to a post, but then all the same buttons do not work in that subsequent post.

In my developer console, when loading wpForo, I get an Uncaught ReferenceError that $wpf is not defined in ajax.js?ver=1.9.4:3 at line 3.

I disabled all plugins but the problem still persists.

I searched the forums and the most common suggestion is to disable all caching and page optimization. I don't use any page optimizers and I disabled any caching, including the browser cache, but the problem persists.

There do not seem to be any problems reported in the Tools>Debug>User Data/Tables/Server/Errors & Issues pages.

I've cleared all the caches using the wpForo Dashboard.

The one thing that will solve the problem is setting my theme back to twenty-twenty-one. I currently use Codex, a child theme of Roseta by Cryout Creations. This theme works perfectly with other forums and other plugins that use AJAX, so I am just trying to figure out what is unique about wpForo. I love the forum plugin and would like to keep using it but this is a bit of a show-stopper.

Let me know if there is any more information that is needed. Suggestions welcome.

Thanks
