"Liking" a post sometimes shows: [ARG:4 UNDEFINED]
This has been happening to me (anyway) for a few years, and I thought it was due to my use of Firefox with an ......., but i just now duped it with Chrome and no ad blocking extensions installed whatsoever.
It's totally random which forum/post/etc.
I click "like" and it shows:

But now I know the like button is a separate product (how odd) and isn't supported any longer.

There's nothing that is new or specific to FlyerTalk about this, or to any particular browser. It's a bug in the underlying software which I've seen on other forums. It's been around for years (possibly decades) and apparently the forum software developers are unable or unwilling to fix it. Which would piss me off a bit if I was actually the one paying for the software!
