I have lost all my Like appearances in my Site

Hi,

I lost sight of the whole Like plugin two days ago.
The program is a good and necessary link to my site
between https://www.konkordanttiset.fi and Facebook.
The program has worked flawlessly for several years, but when a few days ago I went to the settings to crop out article appearances, I noticed that the Like appearances on the home page alone didn’t work, but Like came on all pages. Then about two days ago, the Like manifestations disappeared from every place ?!
I looked on your site that some remedies may be going on.
How and when can I use my Like counter again.

Kindly
