PHP enable error reporting

You can set PHP error reporting on in php.ini file (in case you have access to this file). Set the following lines:

error_reporting = E_ALL
display_errors = On

If you have no access to php.ini file but you can modify .htaccess file on your server (in root of your public_hml folder – your Joomla! site), try to add the following code there (on some servers this option is disabled, so you need to ask your webhosting operator):

# Displaying PHP errors
php_flag display_errors on
php_value error_reporting 6143
