Hello everyone,

anyone can help me? I just got this problem today. Before this my site running smooth with Fastcgi enable but now its show 500 internal server error with below logs. I need to disable php fastcgi in LxAdmin so that my visitor can access my site but when I disable php fastgi, my web performance is very slow with high load to server. I also include the performance screenshot. What should I do?

This are the error log I got:
