Hi, I am new to PHP and facing some problem. I created a website in php/mysql using Dreamweaver. The site was working fine untill my Hosting provider changed the username by which i log-in to the cPanel. Now the site works fine if i access it via the server IP. But if i try to access the same page via URL i get error messages http://www.threadsbigandtall.com/threads-big-and-tall.php?page=products&category=2&cloth-category=big%20and%20tall%20cloths Can somone please help me regarding this issue. I'll really appreciate any help. Thanks in advance.
