Since yesterday, some (but not all!) the questions use the wrong language for syntax highlighting by default. Here is an example:
I can tell that it isn't highlighted as Mathematica because of the different colour scheme, because the comment between
(* ... *) isn't highlighted, and because the word
from in the command is rendered in dark blue.
Just to make it clear to people who are not regulars at Mathematica.SE, the Mathematica colour scheme looks like this:
This problem can be fixed manually by adding
<!-- language: lang-mma -->, as it has been done in this question:
But this should not be necessary. The highlighting should always assume Mathematica on this site unless otherwise specified.
