I've been uploading Wordpress for clients with a couple of minor issues. When the client logs in as the admin and tries to upload an image, they get an error message that they don't have permission. If I go to the "upload" directory, I can fix the problem if I give the IUSR user Full Permissions. However, I would rather do this through the Plesk Control Panel. I have had situations where I loose the permisisons and have to reset them and I end up losing the setting and clients start to call. Is there a proper way to do this via the Control Panel?
