The problem was in the Super Cache plugin options.

Thanks, I will be try.

I tried both options.

No, I have not. I refresh page after Login.

And I have logged into the site at this time.

Site: bereznyaki.org/

Yes, I have. It is the first thing I did, I disabled the cache. It is not the cache.

It happened after I updated the plugin to version 3.1.6 and WordPress 4.7.2

Thank you, very mach
