I have been trying to add MathJax to my blog in the "Ghost" platform on the web (not self hosted). I followed some tutorials and I did find out that if I add the code
into the "blog header" (that I find in "settings"->"code injection") MathJax works fine for displayed math formulas written between
$$. On the other hand there is no way to have the inline math rendered: it doesn't work with the code
[...]. What am I doing wrong?
Here is my test post on the platform.
