This happened lately to a lot of Wikipedians, including myself. See https://phabricator.wikimedia.org/T151770 for the technical details.
Briefly, if you delete all your cookies and log back in to Wikipedia, then this should work. (Deleting your cookies will cause you to get logged out of all your websites where you have accountes, so be sure that you remember all your passwords or get ready to processing a lot of password reminder emails :)

Hello Wikimedians,
Saw the message in this image [1] one week ago but didn't take it serious. Now it seems to be real. I can't Save. The screenshot [1] show messages from frwp and enwp when I tried to save my changes.
Yes, I've tried logging in and out several times.
Best,
- Enock
