I'm getting an odd side-effect here. I switched to the Persona theme to see how it was on my forum. Flushed browser cache with Ctrl-F5, nice new list of categories and everything was fine and dandy (see pic 1).
Then, I clicked into a category, checked out a topic, then clicked my site's logo to return home. The page ended up with the settings applied to categories for Lavender (see pic 2).
If I type (or copy and paste) the site's URL into the browser, and hit enter, it gives me pic 1. This only seems to happen navigating from anywhere in the site using the home link in the site logo (or clicking Home in the breadcrumbs).
Anyone any ideas on what's happening? Do I need to remove all custom classes in categories? I've not seen this before.
Tried Chrome and Firefox, logged in and out.
