# PHP Compatibility issue?

 * Hi, I just used the [WP Engine PHP Compatibility Checker plugin](https://wordpress.org/plugins/php-compatibility-checker/)
   to check if all my plugins are compatible with PHP 8.0, because when I update
   the PHP version to 8.0 on some of my websites I get a critical error and have
   to roll-back to PHP 7.4.
 * Please look at [https:///toerusting.nu/PHP8-issue-duplicator.jpg](https://wordpress.org/support/topic/php-compatibility-issue-12/?output_format=md)
   as an example of the reported issues for PHP8.0. I was surprised to see the red
   crosses in the scan report, from PHP7 and up.
 * I’m not sure how accurate the plugin is for checking PHP compatibility, but if
   there’s even a possibility of any issue, could you please look into this? Just
   to make sure that the Duplicator plugin is not causing the website to crash when
   I select PHP8. And if you have a better plugin or method to check PHP compatibility,
   please let me know.
 * Thanks!

 * Hi [@prodefu](https://wordpress.org/support/users/prodefu/),
 * Duplicator Pro is compatible with PHP 8 and in the same time it supports older
   PHP versions. To support the older PHP versions, deprecated functions work conditionally
   depending on the running PHP version on the website.
 * This results in excising deprecated functions and these compatibility checkers
   plugins detect the deprecated functions as deprecated code.
 * So, this is a false warning from the compatibility plugin you use. Kindly disregard
   these warnings, give Duplicator a try, and let us know if you encounter any problems
   using it.
 * I hope this helps,
 * Thanks!
