Development Policy

Basic Information

This policy outlines the 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: Dec. 6, 2021.

All current Dev4Press plugins support PHP 7.2 and newer, including the latest PHP 7.3, 7.48.0, and 8.1. Most plugins will work with PHP 7.0 and 7.1, and some even with PHP 5.3, 5.4, 5.5, and 5.6, but we are no longer testing with these PHP versions. PHP 5.2, 5.3, 5.4, 5.5, 5.6, 7.0, 7.1, 7.2 are no longer supported by the PHP team, they are potential security risks (because they are no longer updated) and they should not be used!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 7.2, 7.3, 7.4, 8.0, and 8.1.

PHP 8.0 and 8.1 are recent PHP releases, and so far, all Dev4Press plugins should be working fine with both, but if you notice any PHP issues, please report them. recommends PHP 7.4 and newer for use with WordPress.


Last Updated: Dec. 6, 2021.

All current Dev4Press plugins support WordPress 5.3 and newer, including the latest WordPress 5.8 and upcoming WordPress 5.9. In the future, we will test and support our plugins and themes with the latest 6 or 7 major WordPress versions. Depending on individual plugins, this policy can be different based on the WordPress features plugin requires.

Most plugins will work with WordPress 5.0 to 5.2, and some should work with WordPress 4.0 to 4.9 but we are no longer testing with these versions. Also, some plugins have specific requirements that will require different versions of WordPress, so make sure to check out the individual plugin requirements.

When it comes to blocks included with Dev4Press plugins, there is no guarantee that blocks will work as expected with WordPress versions released before the plugin’s latest release. If you use blocks from our plugin, always use the latest available WordPress version!

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

All current Dev4Press plugins support ClassicPress 1.0, 1.1, 1.2, and 1.3. Depending on the ClassicPress development, Dev4Press plugins should work fine for as long as ClassicPress remains WordPress compatible. Depending on the ClassicPress changes in the future, Dev4Press plugins might include code specific to ClassicPress.

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


Last Updated: Dec. 6, 2021.

All current Dev4Press plugins for bbPress support bbPress 2.6.2 or newer.

We support only unmodified version of the bbPress. Forked or bundled versions of bbPress are not supported. BuddyBoss Platform, for instance, contains modified bbPress 2.5.14, and due to the nature of changes made, we do not support the use of our plugins with BuddyBoss Platform!

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


Last Updated: Dec. 4, 2020.

All current Dev4Press plugins support the 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, 8.0, MariaDB 5.5 and 10, but every plugin and theme should work fine with any MySQL since version 5.0.3.

WordPress recommends MySQL 5.6/8.0 and MariaDB 10 for use with WordPress.


Last Updated: Dec. 4, 2020.

All current Dev4Press plugins and themes are tested with the most current versions of browsers for different operating systems:

  • MS Windows: Edge, Firefox, Opera, Vivaldi, and Chrome
  • 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 is no longer supported.
