Things like this can happen if you have had the editor open for too long. Try opening the page a second time in a different tab and see if you can save using the new tab. If so, you could just copy-and-paste from the first tab to the new tab. You could also try copy-and-pasting the contents currently in the editor (i.e. the version the contains your changes) to a plain text document on your computer, reloading the page, and the copy-and-pasting the contents for the text file to the editor. If you are on a mobile device, you can probably use a note-taking app instead of a next file. If you can't do either, then your are going to have to try to remember your changes, reload the page, then make the changed again.
