In enabling MathML via converting the site to XHTML 1.1 compliance, I appear
to have broken the comments system. I need to dig into this further, so the
site is back to being served as text/html, and MathML doesn’t work for the
moment.
More to come.
The problem appears to be that document.write is not compatible with application/xhtml+xml. This means that mt.js can't generate it's content to allow the comment functionality to work.
I'm surprised this hasn't been addressed already.
I rewrote the javascript to be compatible with XHTML 1.1, as mentioned in another post.
I'll try and fully document what I did at some point.
