Exohazard on "[Theme: Sixteen] Cannot link out of my site"

I am trying to create links out of my page using the menus and text options but it automatically removes any button or link that goes out
For example i use a code like

a href="http://exohazard.deviantart.com" title="Deviantart" /a

(i removed the > and < for it to be visible

but it automatically removes the link
