Yes, honestly, I really *DO* like that post!

I think the problem may have been sharing a Wifi channel with one or more neighbours

Could be: if your network was congested, your browser may have failed to download some javascript file that implements single-click 'like' and the effect would be very much like that of having js disabled. This problem is often seen on mobile networks as well, just because they suffer from congestion more.

It's happened to me a few times. But not nearly as often as I've managed to double click the like link, thereby liking and then promptly disliking the relevant post. It would be cool if the system showed a prompt at the third click: "really? You sure this time? This is your last chance."

I haven't seen it since, so I reckon the wifi issue probably was the cause.
