Server port 16080 problem: webserver adds the port number 16080 in the URL

Question

Hello everybody.

On my wordpress website one little thing doesn't work. Sometimes the Webserver adds the port number 16080 in the URL, which leads to an error (network timeout).

Wrong: http://www.example.com:16080/about-us/weekly-program/?month=may&yr=2010 Correct: http://www.example.com/about-us/weekly-program/?month=may&yr=2010

Has someone a "Server port 16080 problem fix"?

Is it possible, that I need to add a ServerName directive to the config file to tell the domain name of the server?

Cheers Juri

!!!update!!! PS: Here is the site configuration, don't ask me to change the 16080 to 80, because that screwes up everyone else's websites... Please let me know what you think of the configuration:
