Why are you testing with PHP 8.0.1? That is about 8 months old at this point and has several vulnerabilities ([https://www.cvedetails.com/vulnerability-list/vendor_id-74/product_id-128/year-2022/PHP-PHP.html](https://www.cvedetails.com/vulnerability-list/vendor_id-74/product_id-128/year-2022/PHP-PHP.html)).

WP version 5.14 will be published with updates. PHP update will be addressed if customers cannot update. The SLP plug-in PHP version was being updated for resisting at the time with the then current PHP version that was compatible according to the WP best practices. Thank you for your information and we will pass it along to the developers team. * Thread Starter [tbob21](https://wordpress.org/support/users/tbob21/) * (@tbob21) * [3 years, 9 months ago](https://wordpress.org/support/topic/fatal-error-php-8-1/#post-15918561) * I see 5.14 is released. It still does not work with PHP 8.1. Only 8.0 and below. * [cicistorelocatorplus](https://wordpress.org/support/users/cicistorelocatorpluscom/) * (@cicistorelocatorpluscom) * [3 years, 9 months ago](https://wordpress.org/support/topic/fatal-error-php-8-1/#post-15924719) * The developer has replied to this issue in the following note back to me * We are currently working on known issues. WordPress **still** does not officially support PHP 8. We develop and test first on the actively supported PHP version before we go back and test compatibility with newer versions; Not all PHP updates are backward or forward compatible so we need to be careful. * P.S. Have you tried this with PHP 8? We have been testing SLP regularly with the PHP 8 environment and have not seen this issue. - This reply was modified 3 years, 9 months ago by [cicistorelocatorplus](https://wordpress.org/support/users/cicistorelocatorpluscom/). * [cicistorelocatorplus](https://wordpress.org/support/users/cicistorelocatorpluscom/) * (@cicistorelocatorpluscom) * [3 years, 9 months ago](https://wordpress.org/support/topic/fatal-error-php-8-1/#post-15939146) * Hello Again, * The developer has put in a lot of due diligence and testing and research concerning the PHP version. ( His [News posts here](https://storelocatorplus.com/wordpress-php-8-1-compatibility/) about this) WordPress issued there own reporting. PHP 8.1 is not fully compatible with WP core. They have clarified the requirements side as such “IMPORTANT: WordPress 6.0 has beta support for PHP 8.0 and PHP 8.1. If used some of these versions may get some Warnings.” Thank you for bringing this to our attention so we can identify to customers the best ways to move forward prior to updating PHP versions Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘Fatal Error PHP 8.1’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/store-locator-le_dac7af.svg) * [Store Locator Plus®](https://wordpress.org/plugins/store-locator-le/) * [Frequently Asked Questions](https://wordpress.org/plugins/store-locator-le/#faq) * [Support Threads](https://wordpress.org/support/plugin/store-locator-le/) * [Active Topics](https://wordpress.org/support/plugin/store-locator-le/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/store-locator-le/unresolved/) * [Reviews](https://wordpress.org/support/plugin/store-locator-le/reviews/) * 11 replies * 2 participants * Last reply from: [cicistorelocatorplus](https://wordpress.org/support/users/cicistorelocatorpluscom/) * Last activity: [3 years, 9 months ago](https://wordpress.org/support/topic/fatal-error-php-8-1/#post-15939146) * Status: not resolved
