  • @Tpojka it worked for me, but i'm still with the error message: Fatal error: Class 'CI_Controller' not found in C:\xampp\htdocs\sistema-emisa\system\core\CodeIgniter.php on line 233 – haRdy Jun 16 '17 at 17:03
  • Check `.htaccess` and `APPPATH.'config/config.php'` to see if any value from online server still there and need to be changed to localhost values. – Tpojka Jun 16 '17 at 17:21

One quick fix needs to be done.

Go to your system/core/Common.php file. And search for return $_config[0] =& $config;

and replace this content with either of the following two snippets:

$_config[0] =& $config;
return $_config[0];

OR

return isset($_config[0][$item]) ? $_config[0][$item] : NULL;

Both of the above given pieces of codes will work.
