Problem with inline equations

Hi, I’ve incurred in a fairly strange problem.
I wrote a post using the standard delimiters ‘$’ and ‘$’ for inline formulas, i.e. I wrote things like $g(z)$: and all inline formulas shown up correctly when seen in the post preview. Nevertheless things broke down when I published it: all inline formulas didn’t appear in the displayed text. Things worked again when I changed the delimiter(s) from ‘$’ to ‘\(‘ and ‘\)’.
Its seems really a configuration problem: all works perfectly in the preview but when the post is published another configuration seem to override the standard one, causing MathJax not acknowledging ‘$’ as a command but only as typed character. How can I find out what’s going on?

Here are my configuration scripts

MathJax = {
  tex: {
    inlineMath: [['$', '$'],['\\(','\\)']],
    processEscapes: true
  },
  options: {
    ignoreHtmlClass: 'tex2jax_ignore|editor-rich-text'
  },
  svg: {
    fontCache: 'global'
  }
};
