About our testing enviroment

Tests were conducted using Apache 2.4.29, PHP 7.2 on Ubuntu 18.04, MySQL 5.7.33 and WordPress 5.9

It is very possible that different versions of PHP such as PHP 8.0, PHP 7.4, or PHP 7.3 could behave differently with FreeStore. Different versions of WordPress could implement the features of this plugin in slightly different ways as well.
