When I posting and trying to insert a link either an external link or a link back to a previous post of mine, the link is not appearing in my preview or published post. I am using the link button, pasting the link complete with http:// and typing in a title. I used both Safari and Firebox on my Macbook Pro. Never had an issue posting using the WordPress app or using Safari on my iPhone or iPad . Is there some sort of setting I have not set up on my laptop?
