Thank you for your advice DrByte. It is most appreciated. This is sort of the conclusion I had come to after reviewing the numerous posts already in the forum, but was not sure.

One more question. Since the SSL certificate has already been purchased from Network Solutions, and this nonstandard configuration of NS with handling SSL certs in ZenCart has been identified......

Can I keep the SSL with NS and migrate my ZenCart to Bluehost without encountering the same issues?

I've already had a brief conversation with BH and they advised I keep the SSL with NS, but based on your knowledge of ZenCart issues, I wanted to ask you as well.
