I have installed the UBB.classic v6.1.0.3 with all the instructions.

I can get the ubb6_test.cgi running all the test without a problem. However in the cp.cgi, when I select forum settings, I get the following error.

Content-type: text/html Content-type: text/html

I have spent many hours trying to figure out what the problem is but I cannot seem to find out.

Please help.
