Hi George,
Frankly spoken, I have no idea...
We are currently not in a position to test php7 compatibility. At the moment, we can go no further than testing on php 5.6.19, which we have not yet done.
I will test whether the plug-in is at least php 5.6.19 compatible and will post the result here.
On the other hand, I am confident that if there are any issues with php7, these can be resolved.
