The site is working and giving content, but the server response code is 500, what should I do?

Question

Nginx

The site works and gives content, and the server response code is 500.
And if I check the admin panel, the server response code is 200 in the admin panel.
Server: nginx/1.10.0
How can this be? Tell me please

Answer 1

Check the permissions on folders and files on the web server.

Answer 2

well, go to the logs and look at the errors,
or you can just return 500 in the script and issue the content in one line of code
