PHP 5.4.9 (cli) (built: Dec 11 2012 01:45:57) , Zend Engine v2.4.0, with XCache v3.0.0, Copyright (c) 2005-2012, by mOo with XCache Cacher v3.0.0, Copyright (c) 2005-2012, by mOo with XCache Coverager v3.0.0, Copyright (c) 2005-2012, by mOo
Now when I try the Site administration > Development > Web service test client it used to work ok and returns the data....
BUT NOW IT GIVES THIS ERROR .....
