It seems that instapress is broken in the newest edition of wordpress.
I'm using the current Striking Theme and I've tried deactivating all other plugins as well and it is still not working. I've tried deactivating all plugins and also switching the theme to the basic Twenty Eleven theme and still no luck.
However with all these tests the next & previous buttons are showing up. But the images themselves are not.
Any word on getting this working? When would one expect an update for this to work again?
