4.7.1 No Thumbnails and Permalinks are Broken!

Holy Cats! Do I have a humdinger of an issue!

Our site, https://www.windsorheightsvoices.net, is self hosted on a brand new Dell server running Ubuntu Server 16.04.1 with all current patches. Theme is: Twenty Seventeen. All plug-ins are most current version available.

Issue: Thumbnails of images (7 in total) do not appear in Media gallery. When link to view any image is selected, the link to the image is malformed. Example: Firefox can’t find the server at http://www.windsorheightsvoices.netsidewalks-in-windsor-heights.. Likewise: When a page is selected from the dashboard, the browser reports the server can’t be found and reports a similarly malformed URL.

Troubleshooting: Server and browser’s caches both cleared. No effect. ALL plug-ins disabled. No effect. While plug-ins disabled, accessed image files directly from server and found no problems with any of them. Proceeded to permanently delete images thru Media page. Closed browser and restarted. Uploaded image files again via Media page. Files reported as present by Media page, but no thumbnails present. Activated Force Regenerate Thumbnails plug-in and ran it. No effect.

That’s it so far. I don’t know what direction to take now. Unfortunately, I don’t have a backup copy of our database that I know to be OK (ignorant, I know). I’m about ready to start pulling my hair out! I hope someone wise shaman can direct my efforts to fix this CF and preserve the meager beginnings of our site!

Many thanks in advance!
