I'm receiving 'RG_Emulation is On' warning in Joomla! 3.x's admin area
This warning is very important for the security of your Joomla! 3.x 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 ); }
