well this is not a photopost error.
Most likely if your talking the vbportal hack I did you have not uncommented the mysql select database statements before and after the hack to select the proper database and then after select back to vbulletin
You need to use those if your using separate databases. Your telling me Bill is getting thrown by that one
This is right on the instructions. Hope it helps
Make sure you set the proper paths and urls and if your database is in a separate one from vbportal to uncomment the mysql lines and fill in the proper info at the top of the file and the bottom of the file
