i have just solve it
edit your 'Loader.php' file and replace this line 976:
function _ci_autoloader()
{
include_once(APPPATH.'config/autoload'.EXT);
with this :
function _ci_autoloader()
{
if(file_exists(APPPATH.'config/'.ENVIRONMENT.'/autoload'.EXT)){
include_once(APPPATH.'config/'.ENVIRONMENT.'/autoload'.EXT);
}else{
include_once(APPPATH.'config/autoload'.EXT);
}
