rafavalles Thanks for the reply! Just wanted to let you know that we have released version 3.0.2 that should fix this issue for other sites using PHP 7.0 (it will no longer crash themπ)
However, as PHP 7.0 has reached its end-of-life status in 2019, we'll update our readme and change the minimum version of PHP for our plugin (to PHP 7.4).
If there's anything else, please let us know π
