I've just upgraded from a 6.2.1 to 6.3, and have patched it to include StickyThreads. While my old 6.2.1 worked fine, I have an odd problem with 6.3.
Everything appears to work fine until you hit the Top Topic button in a thread. Then, you're taken to a page that includes the bare-bones bits of a page (details at the top and bottom, credits etc. In the middle, though, you just get two radio buttons with no labels, and a tiny button gif. Hit the button, and your topic is topped if you select the upper radio button. And for some reason, the topic appears at the top with a colon next to it, rather than an icon. All images are correctly uploaded.
It's clearly a problem with the template - but I can't figure out what. Anyone got any ideas?
