Messed up My Blog

I can no longer click at the top of a blog entry and attach an alert & link to my Boomerfrontrunner Blog on my Facebook page.   I have no idea why or how this change occurred.  Does anyone have a clue what I did or why this happened or more importantly, how I can correct it?  Actually, in a nutshell, this is an indication of my computer skills or rather my lack of computer skills.  I love to write and use my blog as a motivator but do not know enough regarding all the other stuff.   It can be such a frustration and time waster, especially for someone fast approaching 70, who understands quite clearly that their isn't much sand left in the hour glass.
