After upgrading to SMF 2.0.16, It logged me out and I am not able to log in to the forum.
QuoteYou were unable to login. Please check your cookie settings.
I have tried IE, Edge, Chrome and Firefox with the same results.
Any mods installed?
Are you trying the normal, center login form, or the top-left one? (The latter worked for me.)
I am able to log in now - I changed nothing. I'm not sure about the regular forum users though.
Is there something in the database that needs to be flushed?
Do you have a cache enabled? (Not sure if that could be the cause, though.)
can you log in from the header and not from the log in page?
also are you using the default theme or another theme?
I was blocked from logging in from the actual login page (the only method available on my forum).
I removed the "quick login" box sometime ago. I'm using the default theme.
I had the same issue when there was a value for "integrate_verify_user" in the settings table in the database and "Administration Center » Server Settings » Cookies and Sessions » Use basic cookie authentication" was enabled - this will add the entry "$cookie_no_auth_secret = 1;" to Settings.php.
In my case the mod that added the value is Mobile Device Detect (https://custom.simplemachines.org/mods/index.php?mod=3349).
I did not have either of those.
It's odd, but after I installed the patch I immediately restated Apache (to clear opcache). I could not log in on any browser. Then about 2 minutes later it just fixed itself ...
For now, I'm going to mark this as solved as everything appears to be working just fine.

Old topic but just want to say this is what happened to me and fixed it for anyone else searching for a fix
