xlabphil, I'm having the same problem you are.

I already posted a new thread, before reading yours.

I'm getting the folling error on several different pages within UBB Threads, Ver. 5.4.6 running on an Apache Webserver with PHP Ver 4.04:
Fatal error: Failed opening required 'languages/D/logout.php' (include_path='.:/usr/share/php') in /var/www/html/www/ubb_threads/logout.php on line 26

The problem seems to linked with a cookie that my webserver writes as soon as any user logs onto my intranet site. I can delete the cookie and then UBB Threads works fine, however I can't view anything else in the intranet site.

I've tried changing Ubb Threads from cookies to sessions. That didn't help either.

I did not have this problem with the demo version of UBB Threads......

I know I can hard code the path to the language file, but I shouldn't have to do that.

Any suggestions?

Thanks,

Jamie
