Yes... I've actually tried it multiple times.
jos_users has 104 rows
jos_comprofiler has 106 rows
jos_core_acl_aro has 50 rows
jos_core_acl_groups_aro_map has 50 rows
The only users who are visible in my User Manager (both Joomla and CB) are the users who are listed in the jos_core_acl_ tables.
I really appreciate the help... I just want to get my users synchronized right. I'm experiencing strange user permission problems that seem to be related to this issue.
