Corrupted permissions

[CRYSTL]

I got almost all of my forum avatars on server corrupted. They just don't show up and don't download. However, uploads are working normally.

I've noticed some changes in file attributes. Owner is now set to '99' and Group is also '99', but before it was like 'my_login' and 'ftponly' respectively. And I cannot change owner and group myself, because it says, that I have no permissions. I also cannot download these files and delete them.

How these happened, and how can I change attributes back? Btw, is it possible to do that with PHP, I guess PHP have more permissions than FTP-account?

It depends on how PHP is set up but yeah. Can you CHMOD the files from FTP or do you have SSH access?

[CRYSTL]

I don't have SSH access, only FTP. And I can't CHMOD on these files, because owner group is corrupted, so it says I have no permissions.

I've just tried chmod, chown and chgrp using PHP, but it failed also.

I guess I have to contact my hoster.

I would imagine so ....
