I believe they meant that they can't edit their user page; for which the tab is names "Profile". This is based on the combination of the screenshot and the mention of being able to see "view source"; but I could still be wrong.
However, Spookie oh no, if you are indeed talking about your user page, then is it possible you need to be autoconfirmed to edit on that particular wiki. According to the records, this account of yours was registered at 2019-06-19T22:42:23Z (yesterday at 10:42 PM UTC). You will need to wait 4 days from then (June 23, 2019 at 10:42 PM UTC) in order to be autoconfirmed.
