问题
I am trying to set up the admin panel for a mobile app template (with cms) that I bough and after linking the database and trying to access the admin panel I get the following errors, and I really have no idea what to do. Thanks so much to anyone who can help me!

According to your error,
in system/core/common.phpfile change
return $_config[0] =& $config;
to
$_config[0] =& $config;
return $_config[0];
It will work fine.
