I have been able to move a new Theme file, I purchased, to its new location in /usr/share/wordpress/wp-content/themes and /var/www/wordpress/wp-content/themes. However I can not access the theme file itself through my WordPress Dashboard/Theme.
I used the chmod 755 on the file. The new Theme file has the same write/rewrite properties as the themes that WP comes with. I can open the file and see its contents but unable to open the file in Dashboard so I can customize it.
