Today, when trying to go to our forum, http://www2.historischcentrumoverijssel.nl/cgi-bin/ubbcgi/ultimatebb.cgi
, I got the message:
The specified CGI application misbehaved by not returning a complete set of HTTP headers."
Trying to login to the Control Panel shows the same message.
I even don't get the login page.
Our forum is online since years and without problems. Yesterday everything was working just fine. No problem at all.
Somebody an idea ???
