 * I recommend you to check the server settings. $_SERVER[‘HTTP_HOST’] must exist.

 * Never had any such issues with WordPress and the server is more than ok in every

 * I understand that you have got that answer from people hundred of times, but 
   in my case it is true, since this is what i do.
 * I will keep an eye and see how it goes.
 * Thank you
