We just upgrade our wiki to MW 1.28 and the session totally failed.
The symptom is session id changed every time user refresh/visit new page.
Therefore, users can't login nor save edits.
(*"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" / **Sorry! We could not
process your edit due to a loss of session data. Please try again. If it
still doesn't work, try logging out and logging back in.*)
We tried $wgSessionCacheType = CACHE_DB; / CACHE_ACCEL; and 'redis';
as well as set the $wgCookieDomain+$wgCookiePrefix but does not solve this
error at all.
bug reported here but not any
known fix for that.
Anyone have idea on how to fix this bug?
this bug can be reproduced if you login here
