upgrade 1.7 > 2.0 > 3.0 Bellyaches about template_functions.php

How about a fresh installation, and then moving old
/data/pages
/data/thumbs
/data/uploads
/theme/
...
and so on to fresh instance ?

If you have problems with inc/common.php line 26 & 28

Code:

include('template_functions.php');
define('GSROOTPATH', get_root_path());

they may be related with you base directory rule in htaccess file.
