Logo does not show up on my site

The issue is related to your WordPress installation not being configured yet for a HTTPS connection. Therefore the logo will show up as a broken image if you access your website over HTTPS.

You can fix this by following these steps:

1. Go to Settings → General on your dashboard
2. At the "WordPress Address" and "Site Address" settings change the URL prefix from HTTP  to HTTPS
3. Save the settings at the bottom of the page
4. Navigate to the logo setting under Appearance → Customize → Theme Options → Logo & Site Icon
5. Delete the logo from the setting(s) and re-select your logo from the media library
6. Save the settings

Now your logo should be visible, let me know how this goes.
