Facebook doesn't recognize my newest post's link

That’s definitely a Facebook problem. See: https://developers.facebook.com/tools/debug/og/object/

Facebook’s debugger reports:

Object at URL ‘https://tinlanhtre.net/anh-dep-co-doc/thi-thien-5110.html’ of type ‘article’ is invalid because the given value ‘jasmine tr??ng’ for property ‘article:author’ could not be parsed as type ‘profile’.

I’m assuming Facebook is choking on the special characters ??.

Thank you very much, James Huff!

Yeah, I tried the checking page you sent, it’s obviously a problem of Facebook.

Today I tried doing the same thing and surprisingly both 2 links work like charm. Did facebook change their algorithm everyday? Do you have any suggestion that I do something to prevent this problem happen in the future? Should I change the Author name?

Did facebook change their algorithm everyday?

Sometimes I think they change it multiple times throughout the day. ??

I’ve long given up trying to understand the mystery of Facebook. OG tags seem to work mostly consistently, beyond that it either works or doesn’t one moment, then switches the next.

Do you have any suggestion that I do something to prevent this problem happen in the future?

Well, my guess is at the moment Facebook is having trouble with the special characters. I say at the moment, because that could change tomorrow, tonight, 30 minutes from now, who knows.

Does it work if you switch your author name to Jasmine Truong or just Jasmine?

I got it, thank you very much! And, WordPress is so cool ??

You’re welcome!
