Is javascript disabled in Chrome? Are there any errors in the Developer Console? (Ctrl+Shift+J) –  Darth Android Oct 19 '12 at 17:48
    
See my update about errors: there are some. Javascript is on. –  Suzan Cioc Oct 19 '12 at 17:56

From the screenshots, it looks as if MathJax is running successfully but is producing native MathML output (and you're using Chrome 23 or older).

Even though MathJax uses HTML+CSS output by default, this can be changed and will be stored as a preference in a cookie.

Try right-clicking on one of the formulas to trigger the MathJax context menu where you change the rendering mechanism back to the default HTML-CSS (or the SVG-output).

Deleting the MathJax cookie should help, too.

I should add: the reason why MathJax is clearly running is that the first formula is originally LaTeX code. Also, MathJax creates a warning popup before switching to MathML output and setting the cookie. Did you get that? –  Peter Krautzberger Oct 19 '12 at 22:46
    
So this is Chrome bug? –  Suzan Cioc Oct 20 '12 at 22:22

Not really a bug, more a missing feature. Chrome <24 simply does not have MathML enabled (Chrome Canary finally does starting this week, but webkit's MathML support is not very complete yet anyway, cf. Safari 5.1 and later). I would call it "user error": somebody actively changed MathJax's output mechanism via the MathJax menu -- in particular they got an alert box, warning them against it, yet they proceeded it anyway. The results are as expected and can be undone by the user via the MathJax menu. –  Peter Krautzberger Oct 21 '12 at 0:22
