Topic: Making official extensions work with custom theme

The title basically says it all. I currently use Attachment 1.1.19, a slightly modified BBCode buttons 1.4.18, (I added a strike-through button, you see) and Pun poll 2.3.

I recently installed a custom theme, but when I did that, BBCode buttons and Pun poll broke. No image will show where the code insert bar is supposed to be, just buttons. These buttons don't do anything when pressed. The "show poll block" part appears only as static text; it can't be clicked in any way.

The attachment extension still works though, so I believe it's a CSS problem.

So how would I go about changing things around in the extension files so that it'll work with my theme?

Let me know if you need more information.
