problem with site after moved to another server

[zeus]

I recently sold a website (www.domain.com) that contained no php or mysql errors. Once the site was moved to the new server, winxp XAMPP, the site no longer functions correctly. I have setup an XAMPP server on winxp to try to diagnose the problem, but have yet to figure it out.

Example of the problem: www.domain.com
The main page of the site appears to be working correctly, widget titles and links are available and so are the categories and links. After following a category or widget link the center of the page, widget container, is empty. Am I missing something? I've looked over all the scripts and haven't been able to find a clue to why this is working incorectly.

The only error I have found is
Code:
mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/httpd/vhosts/domain.com/httpdocs/profile.php on line 55

upon looking over profile.php and adding print error, I am left with the same error.

I have tried switching between PHP 4 and 5, but still have had no luck. Any ideas or help would be great.

What exactly is on line 55 (and a few lines before)? You say that you have switched between PHP4 and 5, what was the old server running?

Everything in the quotes below is from line 55 and the line above. Your
server
is querying, so I can't explain why this isn't working. I recreated
the server
in winxp and linux and I am experiencing the same problems. Its beyond
me at
the moment.

"$result=mysql_query("select username from users where id=$UserID");
list($row[username])=mysql_fetch_row($result);"
