This looks to me like a faulty upload of files. When you unzip and upload the files to your web host (1&1 in this case) you are uploading almost 2,000 files. I have never yet done this without some failing, so I check my FTP results very carefully and reupload those that failed. At the very least, re-upload includes/functions/compatibility.php and see if that moves you forward.Originally Posted by alias101
As an aside, because of the way 1&1 configures its shared hosting i.e. php is run as a script and MySQL databases are remote from the server on which your Zen Cart is hosted, a Zen Cart with a reasonable number of products or hits will run like a dog. It's a conveneient environment for development and small shops, but if you get serious, you may want to look at one of the hosts that is specifically configured for hosting Zen Carts.
