derick 2024-10-08 15:15 administrator ~0007059	This is known, and expected: https://xdebug.org/docs/compat#compat Using a debugging (development) tool and running JIT (a production feature) at the same time does not make a lot of sense. Your best bet to silence the warning, is to turn off PHP 8.4's JIT in php.ini: `opcache.jit=disable`.
