but i dont know where is database

i have acces to cpanel , admin and ftp server

but dont know how to do it

my friend made me partner i was a mod there , but i need to know vb by myself also

I'm sure the instructor meant to say upload all of the files to the forum root on your server. Which means, via ftp, upload the files to the directory where your vBulletin files are.

If there's a product, or xml file, that gets installed via the product manager in the Admin Control panel.
