You are not logout.
It says 'Error'.

can you press F12 and look in the "network" tab, to look at the content of the "logout" request?

thanks!
i still need to see some important content, not visible in your screenshots.
inside the network, you should click on the red "logout", and then look into "response", like this

are you using nginx or other proxy?
