Not compatible with PHP 7.2

Replies: 0

This plugin uses the function mcrypt_create_iv(), which was deprecated in PHP 7.1 and removed in 7.2. So it will trigger a fatal error in 7.2.

It seems the developer has abandoned this plugin, sadly. I did find this replacement available for purchase though, and it seems to be work fine.
