Question Error if CB avatars in kunena

hello,
After upgrading from 1.7.2 to 2.0.1 i had to disable the integration of CB avatars (Kunena Plugins => Kunena - CommunityBuilder Integration ==> enable avatars from CB).
if I activate it I get this error in the categories of the forum and in my profile CB (see attached file):

Warning: range() [function.range]: step exceeds the specified range in C:\xampp\htdocs\07072012\libraries\joomla\user\authorization.php on line 401
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\07072012\libraries\joomla\user\authorization.php on line 401

i tried on 3 sites and the warning is the same

thanx for your help and for the v2 !

Looks like your database table jos_core_acl_aro_groups is slightly corrupted. Have you installed any ACL components to J!1.5?

Hi,
merci de ton aide/thanks for your help

I just compare jos_core_acl_aro_groups with that of a fresh joomla install and everything is identical.
I never installed any ACL components on my sites.

i had the same error with the CB profils integrated
but with CB profils integrated, the error appears in the cb profil, not in kunena.
