"Document Contained No Data" Error

I'm trying to load a page in Netscape, and I'm getting a "Document Contains No Data" error (in IE it just loads a blank white page). The file is there, the permissions are fine, does anyone know what causes the browser report this error and not display anything? I'm also passing a variable to the page in the form of blah.phtml?var=blah but I don't think that's causing the problem since the page worked before, and I didn't change anything on the file linking to it. Thanks, and please reply directly to me. Pat McCarthy pat@wakeboarder.com (541) 344-4032
