# Cannot save on-page CSS

 * Hey there,
 * For some reason my on-page CSS will not save (when I click the save button nothing
   happens) if I make any change or add anything to the CSS. This happens on every
   single page I have. It occurred sometime yesterday while editing my website.
 * In the JavaScript console the error: “Uncaught TypeError: Cannot set property‘
   isNotDirty’ of null” comes up.
 * Any help would be greatly appreciated.
 * Cheers,
    James
