Is anyhing bad gonna happen if I switch themes? I am using Affilotheme and it is malfunctioning with header issues that I cannot leave the way it is. I have not been able to get any kind support other than someone will get back to me later.
So I am thinking about switching to twenty ten or eleven and see how it is but I have already created an extensive home page, articles and some other stuff that I don't want to lose. Am I OK to switch and can I switch back?
Also I am wondering are the default themes easier to get some help on if I need it?
