ok i uploaded the:

Language folder again,
Mainfile.php and the
header.php
These seem to be the error lines on the page but still the same.
I also tried to upload the same files used in the main folder, it only change the error number from 186 to 161 but still the same.



I had a look at the cpannel and the current versions in there are:

PHP-Nuke is version 6.8
PHP version 4.3.9

don't know if this is where the problem is, being an earlier version than the templates i using which are version 7.5 nuke.
