I have the same problem but my server is already done with:
Can someone help me please??
1. PHP ionCube Loader - can be found at http://www.ioncube.com/loaders.php
, if you don't have it ask your hosting provider to enable it for you
2. PHP Curl library - default for the most hosts
3. PHP JSON library - default for PHP 5 >= 5.2.0
4. Apache mod_rewrite or equivalent (IIRF or ISAPI_rewrite for IIS servers)
