The problem lies in HTML tags, which annoyingly often appear in the text when copy-pasting, are "invisible" and often mess up with MathJax. To fix that you have to enter source code editor (at the top of edit page, you can switch between visual mode and source mode) and remove all things which are enclosed in <> (like  and ). I can edit them out if you want.
