UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 5 Support Unfixable error!

OK, I have been trying to fix this error for 2 weeks now. I upgraded from my hacked 5.45c, losing ALL of my many hacks trying to fix it and even inadvertently deleted some forums. I upgraded to 5.47a. No good. I then updated to 5.47d. No good. Everytime I try to "Update Threads", I get this error:

CGI SCRIPT ERROR:
While executing /www/dodgertclub/cgi-bin/postings.cgi:
Invalid header: Unknown or unsupported header

Script output was:
1 at ubb_library.pl line 474.
Content-type: text/html


PLEASE HELP ME!

It is difficult, if not completely impossible to properly diagnose most UBB problems without knowing which version of the UBB you are using, as well as the EXACT URL to your Ultimate.cgi, (NOT a link to your webpage). Please provide this information. Thanks. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />

I'm going to ask you to use the support ticket system for further support for this issue. Infopop will need to examine your UBB.

Please make sure to turn on your UBB before submitting the ticket.
