Hi,
I am fairly new in joomla I recently develop demo site on joomla & configure it on local host
(win2003, IIS6) everything was working fine on local server since i moved it on remote server I am able to access of all administrator features except Global configuration setting in administrator it says "the website encountered an error while retrieving http://../administrator/index.php?option=com_config. It may be down for maintenance or configured incorrectly." "HTTP Error 500 (Internal Server Error)"
