I am having the same thing happen to us...it seems like it tries to go through our website and then ends up like this and LEAVES the website...and then only to return a few minutes later and repeats the process...

I noticed this from another thread that is no longer in zencart but was in the google catch as mentioned before...it was recommended to put the following in the robots.txt file...
Disallow: /index.php?main_page=cookie_usage
and it seemed to work for Duwane and Woodymon
but I do not want to do anything that would hender the website being indexed, what do you recommend?
Trying hard to get indexed here....thanks in advance to all for any suggestions on this cookie_usage issue...:no:
Also, if you have any suggestions for my website if you could PM me about I would appreciate it, as I am getting a minimum of 300 sessions a day from people, but only about 1 or 2 orders a day right now...
