Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP.

❌ ¿QUÉ SIGNIFICA ESTE ERROR?
Apache está usando un MPM (Multi-Processing Module) de tipo threaded (probablemente event), pero tu PHP compilado no es threadsafe (es decir, no fue compilado con --enable-maintainer-zts).

mod_php no es compatible con MPM threaded si no está compilado con ZTS (Zend Thread Safety).

SOLUCION

Recompilar PHP con soporte ZTS (hilos seguros)

./configure --enable-zts --with-apxs2=/usr/bin/apxs 

Recomendación moderna
En lugar de usar mod_php, se suele usar PHP-FPM (FastCGI), que es más rápido y no tiene este problema, y funciona bien con mpm_event.
