Can't Delete a folder

Ok, this is very odd. I can’t delete, change the CHMOD or edit a folder on my FTP. I need to delete this simple plugin folder for a WordPress (or at least be able to upgrade the plugin) but for some reason I can’t.

I’ve tried via the Web Panel. No delete, no changing permissions.
Tried via Filezilla. No delete, no changing permissions.

What am I doing wrong? I’m using the admin FTP … nothing has changed. I can delete other folders within that WP installation, but just not that one …

have you tried via ssh using something like putty? when in doubt get support to do it for you

Could you tell us the permission and the owner of the files you tried to delete?
