Revision history [back]

Maybe it's just the display that is messed up. Try reloading the page using the "reload" icon or menu item or keyboard shortcut (usually ctrl-R under Linux or Windows, and cmd-R under OS X).

In case something is gone (eg deleted by mistake), you can still recover it using the "History" button at the top of the page in SageMathCloud. This opens a new SMC tab with the history for your worksheet. Use the horizontal cursor at the top to navigate in time through all the versions of your file. You can copy stuff from any version, and go paste it into your file which is still open in another tab.
