Cannot authenticate Google integrations

I cannot integrate any of the Google services.

When I click the “Authorize Goggle …” button, the authentication page is opened in a new tab (while the original tab shows “doc has changed pls refresh” kind of message), and when I authorize and everything proceeds, in the end nothing is changed and the button to authorize is still there.

I can’t backup to google drive or use google contacts. Please help!
