What I am doing is this:
I have Dreamweaver open. Next, I am opening the cart.php file that is located on my local drive. My thought was I would do the edit off the local drive, then upload it to my hosted server.
The error message occurs in Dreamweaver when I open the cart.php file from my local drive. I have made no modifications to the Powerstore files. This is actually the defaul file that came with the download from the original zip file. Only thing that I have done is removed the Read Only attribute so that I can edit the file.
I don't even get past this point without the error message occuring.
