I found a weird bug on my (Wordpress) site today...
Yesterday, my likes were still there. I didn't change any code or did something whatsoever (which is why I hope and guess it's a Facebook bug), but suddenly I saw that my website's page has 0 (zero) likes...
Weird, because when I check my Facebook like button's page, I can see the exact amount of like still there, but not on my like button on the website...
What could be the problem?
I checked with the linter tool and there are no problems at all...
Very frustrating.
Well, I see that this is a known bug and that Facebook will fix it ASAP:

We have a fix for this issue and it will be pushed in the next few hours. We will update this report as soon as the fix is fully pushed and verified.
