These two fields have automatically populated on both of my installation attempts:
XOOPS Physical Path:
XOOPS Virtual Path (URL):

I assume that the physical path is where the installation is getting hung up based on what happens next:
http://paradigm-raiding.com/xoops1.JPG

If I press next, it says this:
http://paradigm-raiding.com/xoops2.JPG

If I try to go back and start the installation over, it gives me the same error about mainfile.php.

How am I to know what the physical path and virtual path are? It seems that it cannot write to the physical path from the error it gave me, but since that field auto populated, I'm not sure how to know what I should change it to.

Please help
