Hi all, this is not a question for the creators(although of course they can help), the question is rather for those who did it, namely, transferred their WP site to Quic, and got stability. At the beginning when I used the template Support for Wordpress HTTP 3 QUIC - #30 , I didn’t see any difficulties, but now I started getting errors. I created a test site in which I put a WP template with Quic https://quic.angellive.ru/

I tried using WP on different sites with similar plugins, but then I created a completely new clean one just with a template theme https://quic.angellive.ru/ And I started getting these errors. All the sites that I tried to use when installing this template give these errors. More errors where either does not occur,I mean databases for example.

My system is Ubuntu server 22.04, Hestia version v1. 8. 12, MariaDB 11.4.3, Nginx 1.27, PHP 8.2 Nginx caching is not enabled
Maybe one of you managed to use HTTP/3 without WP errors, share 
Thank you
