I have tried to set up a modal menu item in my footer menu that when clicked on an article with a message is displayed. I set the menu item with the class modal and linked it to the appropriate article. When I test it on the front end, a blank white box pops up for 1 or 2 seconds and then disappears. I also tried putting {modal}{/modal} around the title of the menu item instead of the class method. Same result. What am I missing?

Yes, autismontheseas.com/ go to footer, and click on Staff Portal Account
I am using Yootheme's Chester template

I changed the Global Setting for default editor to None and still have the issue. Is there a different way I should disable JCE? Can I disable/change it for just this instance?
