title: SOAP: HTTP Not Found when parameter is "SELECT sth FROM"!
body: <p>I' ve a problem with Soap (I'm using it for the first time!).
  I'm trying to solve a problem with SOAP, used to communicate between my site and another.
  In SoapServer (on my site) I have a function called say_hello() that takes no argument and returns simply "hello", if I call it from a SoapClient, also with an argument, it works well.
  The problem appears if the argument passed is "SELECT everythingyouwanthere FROM otherthingifyouwant". I don't know why but it returns "PHP Fatal error:  Uncaught SoapFault exception: [HTTP] Not Found" (404 error).</p>
  
  <p>This started to happen suddenly (or, at least, I don't know the causes). On the server PrestaShop is installed.</p>
  
  <p>Thanks in advance!</p>
  
  <p>P.S. Sorry for my bad english!</p>
