Alot of games fail submiting score

I recently just cleared the high scores in the arcade. And now a lot of the time it doesn't submit. It just sends them to my Index.php page. I'm using vB Advanced mod for the index. My forums is forum.php.

There was something about this in this thread but I didn't really understand what to do. https://vborg.vbsupport.ru/showthread.php?t=155650

Anyone know how I can fix this? o.O

Thanks a bunch.

Theres a text file called (INFO - vbadvanced or another Portal.txt) that comes in the zip with the arcade..That will tell you what to edit in the index.php file...
