The equation editor doesn't seem to be working for me. Whenever I type something in, I get this message where I could previously see the equation: "This is the rendered form of the equation. You can not edit this directly. Right click will give you the option to save the image, and in most browsers you can drag the image onto your desktop or another program." I have tried right clicking but always get a page that says " This site cant be reached
latex.codecogs.com refused to connect."
I have tried the equation editor on various computers as well as in different browsers and still get the same problem. Is is likely this is a temporary problem?
