Alek, Thanks for your help......I haven't fixed the problem but your input has highlighted the problem. Now I understand where this is happening (in the fastcgi parameters) and in what file. If I can discover why it is undefined then it looks like I'll have the problem fixed.

Another note: I think the debug output is on because when I stop nginx and start again....I have no errors, but before if I had an eror in my syntex it would tell me what and where.

I'll read up on the link you gave me, and post my results when I get the problem fixed.

Thanks again for your help.
