which PHP version You guys are using on Dooplay V2.5.5

i am using dooplay PHP 7.4 if i upgrade to php 8.1 then did i have to do any modificaton on it

Just disable error/warning logging in PHP.
Additionally you can enable PHP extensions like Redis to reduce the load on the database.
Verify that you have the Opcache PHP extension enabled.
Install WordPress cache plugin of your choice.

Good Luck!

Don't forget to try php83 too.

I'm currently using PHP 8.2

a mi solo me deja hasta el 8.1
Veré si cambio de liteSpeed a Nginx en el servidor

董TioDonghua華 Nginx con php83 pruebalo!!

Litespeed not good choice?
