I decided the easy course of action for me would be to start over. I removed the MM software but neither of the two auto install bash scripts I found would work. (Including the one I successfully used initially.)
Thanks to Mykle1 and his post (link below) I’m back running again. Later today I’ll modify the config.js file and report back as it may help somebody else in the same situation.

Mykle1’s Manual install how to post is here : https://forum.magicmirror.builders/topic/5274/how-to-manually-install-mm-on-your-pi-for-absolute-beginners

Cheers,
