Title: Problem when running PHP 8 Last modified: August 30, 2022 --- # Problem when running PHP 8 * Resolved [yodergreg](https://wordpress.org/support/users/yodergreg/) * (@yodergreg) * [3 years, 9 months ago](https://wordpress.org/support/topic/problem-when-running-php-8/) * This plugin has worked great for one of the sites I created. Recently the server was upgraded to use PHP 8, and then the checkout page wouldn’t complete the calculation for the form total… it would just be stuck showing a spinning icon. I deactivated the plugin and then the checkout worked fine. We then downgraded PHP for this site and the Payment Gateway Based Fees and Discounts plugin is working fine again when reactivated. * We’re using the Stripe and PayPal add-ons for payment gateway options on this site. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fproblem-when-running-php-8%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [tychesoftwares](https://wordpress.org/support/users/tychesoftwares/) * (@tychesoftwares) * [3 years, 9 months ago](https://wordpress.org/support/topic/problem-when-running-php-8/#post-15971380) * Hi [@yodergreg](https://wordpress.org/support/users/yodergreg/), * Thank you for pointing out this bug. I just tested the plugin with PHP 8 and the checkout process worked fine with our plugin. * Could you please show me the setup through screenshots you have done in the plugin? Also, tell me which versions of WooCommerce and WordPress are running on your site. * Thread Starter [yodergreg](https://wordpress.org/support/users/yodergreg/) * (@yodergreg) * [3 years, 8 months ago](https://wordpress.org/support/topic/problem-when-running-php-8/#post-16005315) * We had temporarily put the production site back to PHP 7.4, but we can try some further troubleshooting on a staging site. We were using the latest version of WooCommerce.

As far as I can tell, that appears to have fixed the problem.

Did the PHP 8 bug fix not get added into the latest plugin update that was released 4 weeks ago? I don’t see a mention of it in the change log.
