A critical issue in the plugin code

Please check the following file:line
wp-file-download/framework/ju-libraries/WPFramework/v1_0_5/Model.php:51

There you can see 'elseif' condition that will always be true.

} elseif ($type !== 'admin' || $type !== 'site') {
return false;
}

In my opinion, there should be 'AND' condition, not 'OR':

} elseif ($type !== 'admin' && $type !== 'site') {
return false;
}

Please fix this ASAP, because it is impossible to work with the model instances outside the plugin.
