Hello everybody…
I am using Zuki for a magazine like project. In each author meta description I have seen that i can use the strong or the em HTML tag, but the a href="…" gets removed automagically. I’ve never noticed this (or needed) before, so I don’t know if it’s a WordPress issue or a Zuki one.
Can you help me ? Thanks …
