Clean the browser cache for this URL following the next steps:
1- set the URL in the browser
2- click F5 + refresh icon ( that should clean the cache data for the current URL )

This kind of issue happens after OpenKM upgrade. The UI have changed in terms of HTML + javascript code and must refresh the old cache data.

Dear jllort
thanks for your suggestions
I followed your steps to clear the cookie of this URL and refreshed the webpage. The problem is still the same after logging in again.
Is there any other way?

In a 99% of the cases the cache is the problem. If this is not the problem then is more difficult identify the reason behind. This is a clean installation?
Is shown any error in the openkm.log file?
