I've been using MathJax until now (working fine), but for a single course I have to use the TeX notation filter instead.
The problem is that when I use single dollar signs, the formula doesn't get converted at all, double dollar signs are converted to inline equations, and so are equations enclosed inand . No matter what delimiters are used, no display equations appear.
Any ideas why this might be happening? Moodle version is 3.3, MathJax filter is turned off for that course, as well as Algebraic notation.
