You need to add a BET on the system, those tabs are not tabs just tab headings.
If you cannot add a bet then usergroup permissions havent been set properly.
Quite frustrating, but well worth the 5 minutes it takes
( in my case : that is )
1.I set vbookie to be used in 3 forums
2.Then in usergroups i set which users could do what ( registered , admins mods and supermods ) each time having clicked save I rebuilt bitfields. ( easiest way to do that is...(see note 1 )
3. then in forum group permissions for each forum, and each usergroup I again set the permissions, and after clicking save on each one, I rebuilt bitfields. ( see note 1 )
Note 1.
Step 1
Open one window with admincp ( with forums link open ) Change permissions one step at a time, so click Administrators under a certain forum, change vbookie permissions, click save ) then move onto step 2
Step 2
Open another window tab ( and in notepad type this out. )
http://yourdomain.com/forum//admincp...buildbitfields
Changing the path to suit your domain. Highlight it, click CTRL+C then each time you have saved usergroup changes in STEP 1 , paste this link into the open tab, hit ENTER
Then go back to Step 1, and move to next usergroup. Repeat until you have done this for all usergroups, and all forum permissions.
