Fatal Error - Call to undefined function

[totalstu]

Excuse my ignorance. I'm new at this and doing it in Ubuntu. I did a search for index.php and found it in four locations.

I'm not sure what you mean by re-uploading. Since I can get into admincp can I just copy the index.php from the /forums/admincp directory to the /forums directory?

Thanks
