Hmm ok, instead of using the above code, use this:
body, h6, #sidebar .widget-heading h3, #header-search input, .header-items h3.phone-number, .related-wrap h4, #comments-list > h4, .item-heading h1, .sf-button, button, input[type="submit"], input[type="reset"], input[type="button"], input[type="email"], .spb_accordion_section h3, #header-login input, #mobile-navigation > div, h1, h2, h3, h4, h5, .heading-font, .custom-caption p, span.dropcap1, span.dropcap2, span.dropcap3, span.dropcap4, .spb_call_text, .impact-text, .testimonial-text, .header-advert {
font-family: ‘TheSerifBasicRegular’, Georgia, serif !important;
}
