When editing a page using visual editor, then switching to source mode, and saving you get a message "The page has been restored"
First, make sure you don't have the 2017 wikitext editor enabled.
- Open whatever page on whatever wiki
- Edit the page using visual editor, here is a link https://en.wikipedia.org/wiki/Special:Random?veaction=edit
- Make some changes, whatever you want
- Switch to source editing mode
- Save the page
- Page gets saved as you wanted, but the message says "The page has been restored".
