LinuxQuestions.org - Dedicated server problem - HTML page doesn't show anymore

Hi all

I hope this is the right place to ask this, otherwise let this be moved to appropriate section.

So, I recently rented a dedicated server running on OpenSuSE 10.3 and started configuring the thing. I managed to make a domain (registered on GoDaddy) to work, Apache, MySQL,... basically all went pretty OK until this evening.
I uploaded some new stuff to the server and suddenly when I try to test it, I only get blank page in the browser.
I lost a couple of hours trying to figure this one out, ... no success, but I managed to find the apache file and this is the message in rcapache2.out after i restart the apache.

Code:

httpd2-prefork: Could not reliably determine the server's fully qualified domain name, using XXX.XXX.XXX.XXX (server's IP address) for ServerName

[Thu Feb 14.....] [error] VirtualHost XXX.XXX.XXX.XXX:80 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results

Syntax OK

Can this be the cause of me getting only a blank page when I try to test the new HTML page... or is there something else wrong? Bear in mind that I am more of a web developer, not server admin so it's still a learning process for me.

Any help would be greatly appreciated
