Help! any apache gurus out there ?

[Eugene Gorelik]

What happens if you try to access static HTML page on this web server ?

If this behaviour is not reproducible with static page then try
accessing some very basic php test page.
If php test page is not causing this issue you need to start reviewing
your production PHP code.
If test php page causing the same issue, then you may want to re-build
(or try different version) PHP module
