I have a new installation of Joomla 1.0.7 + Community Builder 1.0 RC2, works fine.
The configuration in Joomla Administrator:
CB /Plugin Management /SimpleBoard Forum /Published= YES
CB /Tab Management /Forum /Published= YES
In the frontend in the option "TAB FORUM" this message:
Simpleboard forum component is not installed. Please contact your site administrator.
Where is the forum??????
Thank you !!!
I'm sorry my poor english.
