Steps to reproduce
- Download mediawiki 1.28 wmf 6 and mediawiki vendor.
- Install mediawiki.
- THen go to your website where you installed mediawiki.
- Logging in is causing me to get this error
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.
I removed all my extensions to test and still caused that error.
- Logging in should work as it was before.
- Even setting the disable auth manager config still causing me not to be logged in but shows a cookie error instead.
