I went on Samsara Options > General Settings > and changed the logo, retina logo, and the favicon; I placed all of them at top left. In settings, it does say they’ve been uploaded…however, when I go back on the browser, I still see the old Samsara logo on the top left.
After you uploaded the LOGO and favicon, have you clicked “insert to the post” button?
If you did, but it’s still not working, could you please post your wordpress login details with private reply? I will check your settings.
