Geshi errors on the wiki

Hey folks, although I can take a look at the source of a post on the wiki, this is sprouting up everywhere:

GeSHi Error: GeSHi could not find the language mxs (using path /var/www/forum/includes/geshi/) (code 2)
You need to specify a language like this: <source lang=“html”>…</source>
Supported languages for syntax highlighting:
(error loading supported language list)

Just letting you know.

Whoops, this was previously reported but I forgot about it. Will take a look after GDC. Sorry about this.
