Sorry Alex, but the problem after updating to 1.2.6.4 still exists. If you check any box in the user group administration of UAM or in the wordpress user administration, after savin al the boxes are unchecked. You can’t set up the roles ??
Any idea what causes the issue. I also tried to remove and reinstall the UAM plugin. Same behavior. I also tried to create a new user in WP–> same. The boxes you want to check are unchecked after saving the settings.
