Thanks for the replies.

Yes, I fixed the first error message. It was the "" issue in Mainfile.php

I do still get the: ob_start("ob_gzhandler"); problem. It has to do with the gzip compression and from what I could find out is that it's a bug in PHPNUKE. It can't be called more than once, however there are numberous files that call it like: mainfile.php, page_header_admin.php, etc.

If you omit: ob_start("ob_gzhandler");, than you get more error messages, so that's not a fix.

Any suggestions? Anyone encountered that?
