When I install PHPMotion using XAMPP 1.7.3, there is nothing - a blank screen. What should I do in order to find if it is the PHPMotion is not working or the XAMPP is not working?
In PHPMotion package, there is a component PHPShield, which takes as a loader, unfortunately these components only for Linux. As for the version of Windows is not included in the package because it's not free (see http://www.phpshield.com/).
Alternatively, you may be able to download the PHPShield for Windows
Extract the file, then copy to folder
Then restart apache
