Title: PHP compatibility Last modified: August 8, 2025 --- # PHP compatibility * Resolved [saznajmo](https://wordpress.org/support/users/saznajmo/) * (@saznajmo) * [10 months ago](https://wordpress.org/support/topic/php-compatibility-62/) * Hi, * I had to change the PHP version from 7.4 to 8.3. After the change, I got a critical error on the page and realized that the problem was in the WP Forms plugin. After deactivation, the page opens fine. After downgrading to 7.4 everything was fine again and I noticed that WP Forms doesn’t work with any 8.x PHP version. Please let me know what to do at this moment?I use the latest version of the plugin, and other pages properly with these PHP versions on the same hosting provider.

When moving from PHP 7.4 to 8.x, it’s possible that some deprecated code is being loaded, which could be causing the conflict. * When you get the chance, could you please try using the steps in WPBeginner’s detailed guide on [troubleshooting WordPress](https://www.wpbeginner.com/beginners-guide/beginners-guide-to-troubleshooting-wordpress-errors-step-by-step/) to see if it helps resolve the issue? * Hope this helps! If you have any other questions, feel free to reach out anytime. * Thanks! * [philipp242](https://wordpress.org/support/users/philipp242/) * (@philipp242) * [10 months ago](https://wordpress.org/support/topic/php-compatibility-62/#post-18594882) * ```wp-block-code Hi @rsouzaam,i also tried to update my php-Version from 8.0 to 8.1. I also get an error with the WP Forms Plugin. I also get the error with php-version 8.2.
