Yep. the meta_tags.php didn't like that the title of the page has an apostrophe in it. When I changed it back to Zen Cart! it worked again, which allowed me to change templates again.
I'm going to start all over again as you suggest. I hope I know enough to be embarrassed about making it "WAY more complicated than it really is".
One more question before I stop taking up any more of your time, pleae. As php didn't like the apostrophe in the title, is there a syntax that works when you need one?
