Problem : 
--------- 

On localhost (Home computer - winxp pro running apache) - this script works fine. 
On Remote Linux server - The script runs fine (it adds the record to the table) but the redirection header("location:Blog.php");
seems to cause a problem. The script is called and I see a blank white screen BUT the redirection doesnt take place ALTHOUGH the record is being added succesfully if I open the page explicitly using the URL
