I am not going to keep buying upgrades to get the blogsite I want... I bought an upgraded theme, and it changed my header font... I should or you shoud be able to help me, for what I have purchased... I just want the font back the way it was with my header... I cannot find a font tab.... I am self taught and getting very frustrated...I'm not buying anymore upgrades...
