Error 500 cross-origin

Sorry, my mistake , php is working https://www.cxxxi.com/test.php
The domain is cxxxi.com , we tested yesterday [1]

server1.lxxxb.com // hostname
cxxxi.com // website

Yes, it’s the same hCP

nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
apache2ctl configtest
Syntax OK

I’ve installed hCP with multiPHP, then I deleted php 5.6, 7-7.3 (below)

Which config files you need to see about cxxxi.com?
Many thanks
