Well, i got it by myself. Chmod was ok, but chown.. yeah sometimes it is hard to see the easy way

To get the Comments was a hard way, not the import thing, but extracking, username, dateline, comment from a big clear text with up to 150 comments was awful...
Just one little problem is left:
The member link on the username in comments is wrong:
it directed me to: /forums/gallery/member.php
correct path should be: /forums/member.php
This happens only in the comments, link for profil in the uploader data is correct.
