User information on the left
You may notice that on some vBulletin boards User information is listed on the right of the "postbit" (the box that surrounds a post is known as the postbit), as opposed to being listed above the post 'horizontally'.
In order to change the method which is used you need to change one of the Options. To do so read the following:
- Go into your AdminCP
- Select "vBulletin Options" from the navigation menu
- Select "vBulletin Options" from the new menu that appears after following Step 2
- From the list in the right panel find and double click the "Style & Template Options" title
- Look for the option "Use Legacy (Vertical) Postbit Template?" and set this to "Yes"
- Remember that any modifications you had made previously to the postbit template will need to be redone to the postbit_legacy template. Otherwise you may find that some customisations will not appear (depending on the modification).
(Select NO instead of YES in your case)
