I managed to installed PostNuke .750 successfully on my computer which runs Apache and PHP 4.3.2 (Phperl Package). It creates all the tables and I get no error messgae. But when I go to my page (index.php), I get the following error:
Fatal error: call to undefined function: themeheader() in header.php

I downloaded the PN package again (both the zip and tar.gz files) and I tried it on two different computers. But each time I get the same error and I can not go any further. I even used the Swiss Army Knife and it did not fix it either. Then I googled it up and tried to see if other people had a similar problem, but it was not quite helpful. So does anybody know what is wrong?
Best,

Yes, know how you feel Shahins, i just installed PN from the
Fantastico feature in cPanel and when I go to change themes
this is the error I get:

Fatal error: call to undefined function: themeheader() in /home/searches/public_html/training/header.php on line 188

When I opened header.php in my CuteHTML editor it shows that
header.php doesn't even go up to 188 lines. Plus I checked for
any white space above and below the script but it was clean.

Does anybody know how to fix our problem?

Thanks,
Paul
