I tried to submit a request but Cloudflare support is practically inexistent and it would just loop me with advices and I couldnt open a ticket or report my issue otherwise.

[STDERR] PHP Fatal error:  Uncaught Error: Call to undefined method Normalizer::isNormalized() in /var/www/html/wp-content/plugins/cloudflare/vendor/symfony/polyfill-intl-idn/Idn.php:338

This error is generated and causes an error-500 on post.php (greatly affecting wordpress functionalities).

I’m using OpenLiteSpeed on a Debian machine running Wordpress CMS + WooCommerce & Elementor Page Builder

May I ask which version of the Cloudflare plugin are you using? :thinking:

Furthermore, which version of PHP are you running on your web hosting/server with WordPress Website? :thinking:

Ou, I can see another mention of that particular error on WordPress repo too:
