In version 1.31, when I go to the page Special:CiteThisPage, there are two error messages displayed on the page before I have a chance to enter anything into the input box. Maybe these messages are intended to be instructions to the user as to how to use the page, but the way the messages are displayed, it looks like error messages. If these messages are intentional, I would like to suggest removing the first message since it appears before any data has been entered into the input box.
