# PHP v8.3 Compatibility?

 * My WordPress admin is telling me to update my PHP to 8.3 for security and performance.
   After attempting to do so, the site returned a critical error. I must now play
   the game of finding which plugins are not yet compatible.
 * Is this plugin compatible with PHP v8.3, and if not, what is the latest version
   it’s compatible with?

 * Hi [@samusss](https://wordpress.org/support/users/samusss/)
 * I hope you are doing well and sorry to hear you are having this issue.
 * Yes, our plugins are compatible with the latest PHP versions, could you enable
   the debug mode [https://wpmudev.com/blog/debugging-wordpress-how-to-use-wp_debug/](https://wpmudev.com/blog/debugging-wordpress-how-to-use-wp_debug/)
   and then navigate to wp-content, locate the debug.log and find out the line where
   it says fatal error.., please remove any sensitive information like site path
   and then share the fatal error with us.
 * Best Regards

 * Hi [@samusss](https://wordpress.org/support/users/samusss/)
 * I just noticed you are also having issues with Smush [https://wordpress.org/support/topic/smush-php-v8-3-compatibility/](https://wordpress.org/support/topic/smush-php-v8-3-compatibility/)
 * As I mentioned we implement compatibility for all the plugins, for example I 
   use 8.4 on my website without any issues.
 * It could be related to a missing PHP module or some bad configuration in that
   version but the debug mode can help us.
