I use XOOPS 2.2.3 with Extended Profile 0.1. If I edit user profile the changes on assignement of groups to user are not saved. I checked the code of modules/profile/admin/user.php and found a possible solution: at line 149 you find: $new_groups = isset($_POST['groups']) ? $_POST['groups'] : array(); $user->setGroups($new_groups); I removed the second line and now it work. Some line down the code check for group membership change, but it never found anything because of the previous assignement. There is a second bug that cause the field 'Displayname' to always be filled with 'admin' but I have not found the cause. Roger
