We have received feedback that the plugin may crash when an older version of PHP is being used. A quick glance through our code has learned that needed to make a few small updates in order to be compatible with at least PHP version 5.5.0 and were able to test is successfully.
Release 1.5 available now
The latest version is now available for download from our website.
Let us know if you have any feedback because we are keen to make our plugin the best of it sorts and can only do so with your help and patience!
