I'm trying to install a test forum. I have already create the "testvb" folder (password protected) and a new database from the last backup from the original. The problem is when i run the install.php i got this: What I'm doing wrong?
You don't need to run install.php. Just copy the vBulletin files to the testvb directory, make a backup of your DB, and connect the testvb config.php to that database. This might help: Step by Step: Create a test forum based on a 'snapshot' of your live one
