Buttons are not displayed

Hello, for some time, my standard buttons are no longer displayed on my pages when I’m not connected (as an administrator). There is only “share” and the number of shares. When I work on the site (connected), everything is displayed correctly. I already disabled the plugin, I uninstalled and installed … It does not change anything. Can you help me please ? Thank you.
