Direct Access to this location is not allowed

This error comes out if any of the extensions you've installed is not 1.5 Native compatible, even if it seems that it is. Of course that this extension is not AceSEF, if so you would get this error message : "Restricted access".

If this error comes out only if AceSEF is enabled GENERALLY the solution is:

1. OPEN components/com_yourcomponent/sef_ext.php or components/com_yourcomponent/com_yourcomponent.php
2. FIND Direct Access to this location is not allowed AND REPLACE that complete LINE with the one bellow:

defined('_JEXEC') or die('Restricted access');
