I’m receiving ‘RG_Emulation is On’ warning in Joomla’s admin area

This warning is very important for the security of your Joomla and it is highly recommended to turn off the RG_Emulation.

It can be disabled by placing the following line in your configuration.php:

if(!defined('RG_EMULATION')) { define( 'RG_EMULATION', 0 ); }
