Hello, I have been trying to use the strikethrough button when writing a post, and an error message box pops up every time. I can't remember exactly what it says (and I've lost the will to try again) but I remember it was in weirdly dark black/blue/green? colours, with the Mumsnet logo in it, and some sort of very brief message like "Hmm...". Maybe you will know the one I mean.
