Do you think which is the best php based opensource eCommerce system?

Hey!
 
I have created a website for my first client. When I uploaded it to the client's hosting site(netfirms), I had put it in a separate folder under the public_html folder, so that her site was still available and that my new version of the site would be accessible under , for exemple, www.sitename.com/foldername/home.html when I would first show her, then with her approval, I would have replaced her files for mine so that people would see my work when entering the site.
 
Everything worked great, I tested it on Internet Explorer, Chrome, Safari, Opera and all...no problems. Then, one week later, when I was going to work on the site to finish up some details (not having touched it for that whole week) It would only load as a Blank page in Chrome, Safari and Opera, and load as an Error page in Internet Explorer... The weird part is that it wasn't just my site (ex: www.sitenamecom/foldername/home.html) that wasn't working, but the client's site as well!! (ex: www.sitename.com). What was even weirder is that the client has 2 domain names for that one site, and that one of them was working, but not the other one...
 
After doing some research to figure out what the problem is, I thought it would maybe be an error in one of my php files. But I recheck and recheck it again and found nothing. I tried installing a debugger, but had a hard time figuring out how that worked...
 
Then, I thought that maybe it was a problem with the domain name that wasn't working, so I decided to remove my folder that I had added to the clients host site, and tried uploading it to my test domain name.
 
Finally, after removing my files from the clients host, her site is STILL not working...and now my test site works on my computers at home (tried it on two computers and 1 phone, all from the same internet rooter), and again, it works on every browser..but my friends cant see the page when they try to open it on their browsers....
 
So far, 2 can see the site in Internet Explorer, and none (except me ) can see the page in Chrome, safari, or Firefox...
 
Please Help, I do not get why it is behaving this way...
 
Here is the test domain website that I have created: pnd-testsite.com
 
Thanks in advance for any suggestions on what the problem could be. (again, just suggestions on what I should do next, I know that you cannot give me an exact solution, because you do not have the files in front of you...but I cant put a section here, because I wouldn't know which one to put since the problem could be anywhere...)
