Please, can someone help me out. I'm really new to all of this. (uploading/ installing ZC and creating a website). I have the latest version of ZC and have purchased a web hosting through Yahoo. Some one has helped me do these next steps but he is stuck on what to do now. I created the user name and passord for the database and created a folder to put ZC in and went through the steps and did the set up in ZC. but nothing is working. I cant log into ZC or even get the page to pop up to let me start editing ZC. It gives me an error message or the site is under construction. when I try to put the URL in below(www.mydomainname.com/shop/admin/login.php)

Please can someone give my advice or let me know what could be wrong.
