This is my first attempt at creating a store and much of this is new to me. While setting up my settings I clicked on the template editor and everything was highlighted green. I cannot not find how to undo or turn off the template editor, please help.
Try going to Design/Design mode.
Make sure both Translation Mode and Design Mode are turned off.
I believe the green (but could be wrong) is from the Translation Mode being enabled and it's highlighting everything that is a language variable.
Others who use Translation mode might be better to advise, but this might get you started.
