    Hello,

    I still have a couple of sites running under PHP 7.6 and would like to move on PHP 8.xx.
    I know WP core will have no issues with that but what about installed plugins?
    Is there a way/plugin you recommend to test installed plugins’ compatibility?

    Thanks.

  • PHP 7.6 does not exist, I assume you mean the much older PHP 5.6. In this case, an update is only really time.

    It’s best to test this on the project itself. You could set up a copy in a separate hosting area in your hosting, where you can set the PHP version separately. Then you can test there whether and which plugins are compatible with PHP 8.x. You can ask your hoster’s support team how you can set up such an area.

    Alternatively, you can also run the test in a local copy of the project on your own computer. Here too, there are various solutions such as MAMP, XAMPP, localwp etc. for running WordPress.

    To check for plugin compatibility, visit each plugin’s page in the WordPress repository to confirm whether it is compatible with PHP 8.x. Look for updates or notes about tested versions. Additionally, before upgrading your live site, clone it to a staging environment, update the PHP version, and use a plugin like “Query Monitor” to check for errors.

    Thanks to both, well noted.
    I misspelled current version, it’s 7.4 not 7.6.

    In the meanwhile I also found this plugin that might help:
