I'm learning how to write a plugin. My plugin is a google map that places markers based on the selected criteria. It works fine. The problem is that it interferes with one part of the theme I'm using. The theme is called Superb. The theme has a uBillboard, basically, it's a slider. For some reason, my plugin prevents the uBillboard from appearing-- the first maybe 30 pixels of the image are visible.
I'm not sure where to begin in order to debug this. What should I be looking for? What are common reasons for plugins interfering with themes? I can post code, but I don't think that it makes sense to post the whole theme and my plugin.
