Out of date? Does not work w WP 4.5

I really wanted this to work and struggled with it for some time, but no go on anything.

No updates for over 2 years, only tested to WP 3.9 and the 5 star reviews are from 2 years ago.

Love the idea and can′t find another one like it, but you might be wasting your time.

If I′m wrong, I′d love to know how to make it work!
