Basic Information

This policy outlines development methods and testing of Dev4Press plugins and themes.

Due to the wide range of different WordPress, PHP and MySQL versions, it is impossible to support every version of these, and many of the plugins and themes features are dependent on the WordPress development and available functionalities.

Because of that, development practices and policy is changing over time, and here you will always see an updated version that follows the development of WordPress. This development policy relates to current plugins on Dev4Press. Legacy and retired plugins and themes development are not ongoing, and their system requirements are not updated.


Last Updated: 11.02.2018.

All current Dev4Press plugins support PHP 5.6 and newer, including latest PHP 7.0, 7.1, 7.2 and 7.3. Most plugins will work even with PHP 5.2, 5.3, 5.4 and 5.5, but we are no longer testing with these PHP versions. PHP 5.2, 5.3, 5.4 and 5.5 are no longer supported by the PHP team, they are potential security risks (because they are no longer updated) and they should not be used! All Dev4Press plugins and are tested with the latest releases for PHP 5.6, 7.0, 7.1, 7.2 and 7.3.

This policy will remain in effect for one year, and after that, PHP 5.6 support will be dropped. recommends PHP 7.0 and newer for use with WordPress.


Last Updated: 11.02.2018.

All current Dev4Press plugins and themes support WordPress 4.5 and newer, including latest WordPress 4.9 and upcoming 5.0. In the future, we will test and support our plugins and themes with the latest 6 major WordPress versions. Once the WordPress 5.1 is released, we will stop testing with WordPress 4.4. Depending on individual plugins, this policy can be different based on the WordPress features plugin requires.

Most plugins should work with WordPress 4.0, 4.1, 4.2, 4.3 and 4.4 but we are no longer testing with these versions.

This policy will be updated each time new major WordPress version is released.

All current Dev4Press plugins and themes support same MySQL versions as WordPress does. But, we also test with community MySQL replacement projects like MariaDB. In general, we test with MySQL 5.5, 5.6, MariaDB 5.5 and 10, but every plugin and theme should work fine with any MySQL since version 5.0.3.

WordPress recommends MySQL 5.6 and MariaDB 10 for use with WordPress.


Last Updated: 11.02.2018.

  • Android: Chrome and Opera
  • Linux: Firefox, Opera, Vivaldi and Chrome
  • MacOS: Firefox, Opera, Chrome, Vivaldi, and Safari

We test using the latest stable versions of supported browsers. Our plugins and themes may function correctly in older or other, less popular browsers, but we only officially support listed browsers. We support current and previous versions of all supported browsers.

MS Internet Explorer 11 is supported, versions 6, 7, 8, 9 and 10 are no longer supported.
