That is Wikia session hijacking prevention thing. Logging in requires a password and gives a session (browser cookie), browsing with this session works via this cookie, you can do stuff as a user, stealing the cookie value (and thus the session) is then session hijacking (someone can do stuff as you, but can't change password and actually steal the account). That thing is known to have a lot of false positives, it will prevent actions even if there is no actual hijacking, I don't know how it works, but I'd assume it's via looking at changes in accessible parameters ( from my observations the cookie is static, at least I remember using it in a bot and it was working for a long time, since requests are mostly the same; right now I'm use a different bot, requests are very different from browser, and Wikia always force logout me in browser when I edit with it :/ ). So what you can do is maybe restrict those changes and restore browser state, e.g., for chrome:

1. do the hard reload (Shift+F5, "reload the current page, ignoring cached content") or empty cache and hard reload

2. clear wikia cache and local storage (chrome://settings/content/cookies, search wikia, remove all) and login again.

Other than that, not sure, I only remember seeing that message like once or twice.
