Today, I install a new VPS on Debian 11. Everything is ok until I install WordPress
Internal Server Error
Oops! Something went wrong.
The server encountered an internal error or misconfiguration and was unable to complete your request.
Error Code: 500
Check the .htaccess file.
If there is a problem with this file, it can cause a 500 error.
You can rename it, restart apache and nginx, and check if the error persists.
check the error logs for the apache2 server and nginx server too. You also need to check the error log for WordPress so you will have a better idea of where the error is located. The error indicates something wrong with servers unless you customize the installations of HestiaCp.
