Ciao Niccolò, grazie per la risposta.
I prefer keeping comments in english so that everybody can join the discussion if they have the same problem 🙂
I’ve been looking around the web, and interestingly I found out that it’s not just me, it’s kind of weird, since it’s an aleatory issue, if it really was for the meta tags, it would not work every time, but strangely the latest few days, the succes ratio of loading the like button has increased. Let’s say that if one week ago I was getting 1/30 chance of seeing the like button appearing, now I get it 20 times on 30 tries…
My guess is that something’s going on at Facebook, maybe they’re working on the code or even trying to fix this, I can’t find anything regarding this.
If anyone have any info about this, please let know!
Thanks.
