Some years ago I set up a small website using Grav, and included the TinyMCE plugin since the user didn’t want to edit markdown.
I’ve had to port the sight to a cloud server, and ended up installing everything from scratch and copying over the user pages over. Everything works fine, and I can edit the markdown via the default MD editor, but when I install the TinyMCE plugin and activate it, the markdown looks like just a long string of text without linebreaks.
Does the TinyMCE plugin require something like the showdown.js conversion layer to convert markdown to HTML? As far as I can see the original site didn’t need that.
