1-Create a php.ini file if u dont have one there it is.. 2-Add this php.ini file to administration root 3-You had to turn off the "define( 'RG_EMULATION', 1 )" to "define( 'RG_EMULATION', 0 )" which "0 = OFF" and "1 = ON". To do this you must go into your "globals.php" file in your Joomla! directory. Thats it your "PHP register_globals setting is `ON` instead of `OFF" error will solve. Yesterday night i setted up joomla lastest version and had that error but it was solved.. Someone may need it.
