- Error Reporting. This parameter sets the level of error reporting to be used by PHP on the Joomla site.

Tip: Should your Joomla site fail to the extent that it is not possible to use the administrator page to activate error reporting, you can switch on full PHP error reporting by editing the configuration.php file. Changing the $error_reporting parameter in that file to a value of 'maximum' is the equivalent to setting Error Reporting to “Maximum”.
