502 Bad Gateway nginx

[Szer0P]

Hello

I have a problem with my server also when i get this problem i restart my server and the services for example nginx and httpd and get than work but this time the problem doesent resolved

i see that
PHP-FPM 5.6.14 by OS vendor
PHP-FPM 5.6.14
are not avalible is this the reason ? i coudnt restart any of them and i think that nginx works on php fpm


i think the problem is there:

Starting php-fpm: Failed loading /usr/lib64/php/ioncube/ioncube_loader_lin_5.4.so: /usr/lib64/php/ioncube/ioncube_loader_lin_5.4.so: undefined symbol: execute
