One more request for help
If someone could suggest a specific way to make the blog title image work to bring you to the home page, that’d be most appreciated.
Update, I think I fixed most of it.
Thanks in particular to commenter “M”, who got me on the path to the fix, removing the inline CSS that the theme put in place via a php function (huh?). Thanks also to @optiqal, @pogowasright, @bwittorf and @37point2 for looking at the issue and offering helpful suggestions.
