Question Cannot create new topic - Fatal Error: Class 'KunenaSpamRecaptcha' not found

We've been doing some maintenance on our site, but now we cannot create a new topic in any category on our forum.

Here's the error:

500 Internal Server Error

Fatal Error was detected!

The error was detected in the Kunena Component.

Fatal Error: Class 'KunenaSpamRecaptcha' not found in components/com_kunena/views/topic/view.html.php on line 194

Any ideas? I cannot seem to find anything about the KunenaSpamRecaptcha. Thanks!

fix:

github.com/Kunena/Kunena-Forum/pull/4944/files

Thank you! I removed the code as instructed, and no longer receive the error. However, now I click the "create new topic" button and the page simply refreshes, with no new topic created.

Thoughts?

There are some issues with joomla sessions.

Try this:
backend - system - global confgurations - system tab - Session Settings set to database

I've tried the Session Settings as .php and database, neither has an effect.

Thank you!

ok, then turn of memcache cache
