Hi All,

   I have been trying to download the new version of abantecart but there is an error message saying "There has been a critical error processing your request. Please check AbanteCart and webserver error logs for more details. You can check error log in the control panel if it is functional. Otherwise, refer to error log located on your web server". How do i upgrade to the new version?
