Is your php code returning 500 Internal Server Error instead of PHP erros page?

Is your php code returning 500 Internal Server Error instead of PHP erros page?

Lets try this header in the first lines of your .php page:

<?php

error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
ini_set('display_errors', 1); 
ini_set('display_startup_errors', 1);

?>

You can also edit your

/etc/php.ini

with this parameters to make this settings permanent.
