After updating grafana from v6.7.1 to v7.0.5


We have updated grafana running on AWS EC2 from v6.7.1 to v7.0.5.
After updating, the dashboard was displayed without any problems, but once I signed out and then signed back in, the dashboard disappeared.
Do I need additional settings in the grafana.ini file?

Thank you

Hey, Guys

It was a problem with the cookie path.
I solved it by changing login_cookie_name in grafana.ini.
Thank you very much.
