re., downloads - I was responding to the post by pennilane who asked:
Can someone please tell me that if you offer digital downloads that the download folder must be moved to the 'root' folder and the config files changed to reflect this. The person who installed my store also deleted the 'pub' folder. It would be interesting to find out if this was the cause of the problem.
This implied (to me at least) that they were using digital downloads. Hence my answer, but I also did say.
If "Download by redirect" is not used then the files are served directly from the 'downloads' folder.
With regard to the multiple sessions from the same person, this may or may not be a bug in Zen Cart - but I tend to think that it's not a bug. Which ISP are you using to connect to the Internet?
If you are using AOL then that would account for the multiple sessions problem, as AOL cannot follow a session to save its life. Before delivering up a web page to you AOL caches it on its servers, but it caches each element of a page separately on different servers in different locations, and that can mean 20-30 items being cached by AOL for every page shown - each one generating a session.
I have shown this to be correct by viewing what AOL does when it visits a site by looking at the web stats.
