Found the fix for "Error: errors.Not a valid license key".
in the file "install/controllers/ManageController.php"
Remove this from line 358 to 374.
if ($db instanceof Zend_Db_Adapter_Abstract) {
try {
$row = $db->select()->from('engine4_core_settings')
->where('name = ?', 'core.license.key')
->query()->fetch();
if (empty($row['value'])) {
throw new Exception('Missing license key.');
}
$warehouse = new Engine_Warehouse('/php-site/license');
$warehouse->get(array(
'key' => $row['value']
));
} catch (Exception $e) {
$this->view->licenseError = $e->getMessage();
}
}
This removes the license check and allows you to use the Packages and Plugin manager.
