Using WP 3.5.2, WP Super Cache 1.3.2, and WP Touch Pro 3.0.7. I have followed the instructions 3 times now...TO THE LETTER, and am still getting a notification that WP Super Cache is not configured properly.
What a waste of time and money. I should have stayed with the free version, at least then the mobile version did not show up on desktops and vice versa.
Support is not very helpful either. Why not just have a nice video showing exactly what to do, better yet, why not design the plugin into work with the most popular caching programs.
