Okay just installed a new clean version of Joomla and Community Builder (newest versions)

I have the CB Login on my homepage. Now when anyone tries to register or while i'm in the administrator side of things and I go to Community Builder > User Management it just goes straight to an error page

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, advancedsupport@ensim.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Anyone experience this? If so any ideas how I can fix this.

Just a note, if I use the Joomla "Register" it works.
