Sounds like a database connection error, or the PDO library may be missing. Which version of Gibbon, PHP and MySQL are you running? In Step 1 of the installer there is a check for extensions like PDO, did any of these checks indicate a red X rather than a green checkmark? Also, can you check your PHP error log to see if there's any more specific errors in there?
