Edit: Well, I’m not entirely happy with this theme, but it’s the best of a BORING lot. At least all the content is here (I think) and nothing’s obviously broken. There may be more customization to come. Or maybe not.
My host has decided that some code that’s part of the theme I was using for this site is similar enough to malicious code that it’s removed the file (hence the errors at the top of the page on the original theme). So, I’m on the search for a new theme. Please be patient while I deal with this annoyance. Thanks.
