I need someone to help me with this one.
Sometimes when I try to unnistall components (in my se Galleria and dbquery), Joomla gives me an error. The component is "removed" from the site menus and administration but the files aren't deleted. When I ftp and try to delete I get a permission denied error. I think that, and correct me if i'm  wrong, this happens because when someone installs a component trough joomla the creator and owner of the folder is a php file (on linux servers). Is there a way around this and delete the unnecesary files?
