Reply To: unable to insert hyperlink in post

The line that it’s coming from is line 2857 in your css –

.epik-blue .head-wrap a,
.epik-blue .welcome a,
.epik-blue .home-feature-bg-dark a,
.epik-blue .author-box a,
.epik-blue .footer-widgets a {
	color: #fff;
}

But you could add that code above and it would fix it as well.
