Question 500 Error in Forum Configuration and forum

I don't get the connection between the two but you are the man..so I'll give it a shot.

Uninstalled, cleared cache. still no go. 500 error on the forum Configuration page.

Thanks for your help Solves, I will have to get with you later regarding our discussion on PM.

Band-aid solution used: involved disabling login form on Kunena pages.

Backend issue remains (unable to use Forum Configuration GUI) - possibly this is related to Community Builder; we cannot say for certain.

Importantly, end users are now able to interact with the forum on the website.

And I can sleep well tonight!

I think I will uninstall CB, as we discussed the data is not lost in this uninstall. Once removed I'll see if I can get to the Forum Control on the back end, set the integration settings correctly and reinstall CB. Making frequent backups along the way...

Thank you for your help Micheal! You rock!

Update:
Finding that setting the "integration_login" to anything other than None crashes the site.

No progress on getting the Forum Configuration page to load. I still suspect there is some issue between the sessions and CB.

Most likely there is still that fall-out from the abortive J! 1.6 installation to deal with, too.
