| Refresh/ Clear Cache/ Restart/ Delete Temporary Files/|
You may need to clear your cache (delete temporary files and cookies), or Refresh, or restart your computer. Try the Refresh button (F5 or the double-arrow icon up above) or Ctrl-F5 first, then consider the cache. Sometimes our computer will hold an old memory of our blog and won't spit it out! See if you can shake it loose.
The preceding may work wonders (sometimes) for links or icons that have disappeared from your screen.
Of course, your trouble may just be a Blogger Quirk due to your server being disrupted or worked on. You have my pity, but that's not worth much.
For those of you unaquainted with the cache or the "Temporary Internet Files", go to the Tools tab up above and click it. At the bottom of that revealed menu will be "Internet Options". On that menu you will find where to click to Delete Cookies or Delete Temporary Internet files (which is the cache). I know, it's double lingo for the same stuff!
It never hurts to restart your browser or even to change your browser (temporarily) just to see if it is easier with the particular problem that you have.
