From where can I check the exact version of my vBulletin?
You can find the exact version of the vBulletin you are using:
– Via the AdminCP of the script already installed. The exact version of your vBulletin is displayed at the top left of the page ( please refer to the following figure).
The other way to find the exact version of your vBulletin is to log into your vBulletin customer area you acquired vBulletin from.
