I have just bought a VBulletin Hosting Package but I do not find Vbulletin installed on my account
Siteground provides one standard shared hosting package which is perfectly suited for installing and running a VBulletin forum. However we are not Vbulletin affiliates and do not distribute it on our accounts. In order to have Vbulletin installed, you first need to get a license from the Vbulletin's website.
If you have problems with its installation you can request our assistance from your Customer Area, Get support, Script installation.
