Good day

I'm using the Kindle template on a community site using Community Builder. There are template conflicts that I need to sort out but I don't know where to begin (Community Builder support forum isn't able to support Joomla template issues). But they did tell me that the template is causing their buttons to display incorrectly. Where do I fix this?

Please see the screens... I need to change either the button background or the button text.

Thanks!
