I downloaded the XF and XFMG files, zipped them, uploaded them directly to Cpanel, extracted, upgraded. Now all avatars and media gallery images are no longer showing, instead giving a 403 forbidden message. I went though old threads here and checked the permissions on data and internal data - both were 755, so I changed them to 777. I've CHMODed all avatars and avatar folders to 777. And yet the problem continues. Any advice gratefully received.
