The settings are a little tricky, because they can be done on user side as well as on admin side.
these settings are important for you in ACP:
- Allow users to modify their Profile-Settings
- Make Profile Settings below default for ALL users and new users
If you change tab position in ACP, it will only apply automatically if you dont allow users to modify their profile settings.. then the settings in acp apply automatically... or
you can change default behaviour by setting Make Profile Settings below default for ALL users and new users
when saving it will change default settings for ALL users and for new users.. (the setting will then jump back to "NO") but the default settings for all users will have been modified and will be those you set in ACP.
BUT, from that moment on, a user can go to his profile settings in UCP and put the tab back first if he wishes (If you have set allow users to change their profile settings to NO, then he cant change the position of his tab.
