As I have some issues with installation I wonder if CB 1.9 and Joomla 3.1.5 are fully compatible?
For example the plug-in "ratingfield" does not show any parameters and it won't reinstall.
Is it best to use from CB 1.9 (Groupjive and Subs) compatibility point of view, - Joomla 3.0, 3.1 or even 2.5.14? Maybe wait for 3.5?
Cheers!
