v1.5.7 now fully works with php 7.
You have Gingalley for providing the php 7 hosting and also myself to thank for this!

This is entirely optional, but does mean that I am able to spend more time providing support and fixing issues than I would normally as working on this plugin doesn’t pay the bills.
