Dr Byte, thanks again for your rapid response. RodG, apparently your comment that I must "reset it once again" is pertinent, but I don't understand what you mean by that phrase. The loss of link from my browser to the Zen Cart application occured when I used the "edit" function in MySQL admin to change the db password. Apparently I changed it to something other than what I had previously installed into the config.php file. So I noted the password in the config.php file and then returned to the aforementioned "edit" utility and changed the db password to what I had noted in the config file. Didn't help; which I think is what RodG predicted. So RodG's subsequent comment, that I must "reset it once again" is what describes the situation; but I don't understand what that phrase means. Thanks again for your attention to this self-inflicted injury, so to speak.
