Hi. Sorry for the prolonged silence.

I honestly have no idea how to reproduce this. If you could describe how you got this error, that would dramatically increase the chance of it being fixed.

Sorry, I can't remember exactly what happened.I seem to have updated some of the plugins, then something went wrong and I hit the submit button.

markdown-preview-plus 3.11.0 and emmet 2.4.3 have Have the same Keybindings.Not sure if that's the reason.

[lierdakil]

Probably not.
