Thanks so much for your help! I really appreciate it...I'll buy you all a cup of coffee (or several) once this gets up and going...I've followed your instructions and emailed the support team at Webmasters.com asking them exactly what you said to ask...they're pretty good about responding quickly.
just to clarify though, originally I tried installing/using phpCart by Webmasters, but that was so complicated and the support team only gave me vague, redundant answers and didn't help me solve anything. so I am trying zencart, which so far I like a whole lot more...i'm sure i'll love it once i can access my Admin! :smile:
anyway, the phpCart required me to purchase an SSL folder (not certificate! that, apparently, is different), for which the address they gave me is: https://secured.com/~f3489/ ...what I'm supposed to do with that, I don't know. how it connects to my site, I don't know. if I need to cancel that though and purchase an SSL certificate instead in order to use zencart, i'll do that...just say the word.
