When I add a category page to my menu the page comes up and starts with something that looks like this:
upcoming" class="page-title category-title"> Category Archives: Upcoming
There is broken html. This is theme dependent, but I have discovered just now that it is browser dependent. I don't see it from Chrome or IE8. But I do see it in Firefox (most up to date). The html is definitely broken in Firefox, but not in the other two browsers (used View Source and equivalents to check.)
I have been seeing this on various of my sites for several months. My workaround is to use the category/archive page templates that come with my themes, but if I have a theme that does not do that then I am SOL.
Themes that misbehave for sure are: Weaver and Nova from Elegant Themes.
What is going on here?
