CodeIgniter Error: variable references
Try this one:
Change it in your Common.php
if (count($replace) > 0){ foreach ($replace as $key => $val){ if (isset($config[$key])){ $config[$key] = $val; } }}$_config[0] =& $config;return $_config[0];See also here , for more reference : Only variable references should be returned by reference - Codeigniter . I hope this helps.
In Common.php Change this
return $_config[0] =& $config;to this
$_config[0] =& $config;return $_config[0];Problem is with assigning and returning data.
If your code is still not working, then try this.
$_config[1]=& $config;return $_config[0];
