1)
First go to maintenance / update counters:
Click the button "rebulid styles" with the options set to:
- "Check For Styles With No Parent" set to "yes"
- "Renumber all templates from 1" set to "no".
Did this help? If not, then proceed.
2)
In the admincp, under vbulletin options / style & language settings:
Set "default style" to what you want it to be.
Then go into styles & templates /style manager:
Check the checkbox to the left of the style you want the users to have.
Then, (at least until you solved this problem), uncheck the checkboxes to the left of all the other checkboxes, so that the users cannot select those styles.
Did this help? If not, then proceed.
3)
Then go into forums & moderators / forum manager:
Edit each of the forums and set "custom style for this forum" to "use default style".
Or, you can set "Override Users' Style Choice" to "no" for each forum.
Freferrably you do both.
Now your users can only see the forum with the default style you selected above.
Did this help? Really hope so.
Two question:
- Can your users see the information field "Currently Active Users:"?
- Have your users selected to "browse invisible"?
Good luck!
