XF 2.0 Cookies Required Error Message after version 2.1.0 install

[rbirkey]

I just completed the upgrade to version 2.1.0. When I try to login to my admin area, I get a pop-up that says - "Oops! We ran into problems. Cookies are required to use this site. You must accept them to continue using the site." I cannot login to my Admin area. Any ideas how to fix this?

I assume you mean 2.0.10?

Sounds like it could a issue with Varnish if that is enabled on your server.

Yes, 2.0.10 and my server uses Varnish... and I've not had this issue before. Why now and what would I do to correct it?

 

[Ozzy47]

I would disable it and see if that is the cause.

I turned Varnish off, refreshed my browser, then was able to log in. I have turned Varnish back on and don't have any more issues. Thanks...

It could have been just the caching being a bit aggressive, glad it's sorted.

I'm having this issue as well, I have no idea what varnish is, but I'm unable to log into my own site on mobile because of it.
