Actually, this would coincide exactly with when I upgraded the forum to 2.0.6. Tapatalk are showing their plugin tested for 2.0.5, but not 2.0.6. As 2.0.6. was a security patch release, you might just have to live with it until they get round to fixing it.
This is why we don't want to just install plugins for every little thing that someone might think sounds fun. (I don't include Tapatalk in that, I know a lot of people use it - I'm just making the point.)
