Warning messages at the top of admin pages

I have these messages at the top of my admin pages and not sure what to do…

As well as this one regarding Add link to Facebook:

Please help! Not very technical but I can get around and I’ve been using wordpress for a couple years without any real issues other than this.
Thanks in advance.
