title: Can't log in to mediawiki: canceled as a precaution against session hijacking?
body: <ol>
  <li>I'm using a private mediawiki hosted on AWS EC2 instance for years</li>
  <li>I thought something gone wrong with some extension, specifically stopping in the middle of math rendering, so I tried to reload the page with Google Chrome browser's cache were all erased.</li>
  <li>Right after that, I can't log in seeing this message "There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking. Go back to the previous page, reload that page and then try again."</li>
  </ol>
  
  <p>I tried,
  1. restart apache server
  2. tried <a href="https://stackoverflow.com/questions/25317403/mediawiki-sessions-and-cookies-not-working-on-multi-server-behind-cloudflare">MediaWiki sessions and cookies not working on multi-server behind CloudFlare</a>
  3. tried <a href="https://stackoverflow.com/questions/38553500/mediawiki-cant-login-after-password-change">Mediawiki, can&#39;t login after password change</a>
  4. tried "go in your LocalSettings.php and at the end add the following code of line :session_save_path("tmp");Create a folder "tmp" in your wiki installation directory. give rights 777 (permissions)" as in <a href="https://www.mediawiki.org/wiki/Topic:Pjby0sdeg3e60rfy" rel="nofollow noreferrer">https://www.mediawiki.org/wiki/Topic:Pjby0sdeg3e60rfy</a>
  5. checked the server's hard disk storage, but it has free space of way more than 3.5gb.</p>
  
  <p>How do I fix this and is there any way of disabling this really helpful "PRECAUTION" feature?</p>
