Adding YouTube videos to SS

www.covenantsuncitywest.org/

Please check the sermon form. For some reason SermonSpeaker builds the link like this: www.covenantsuncitywest.org/%20https://youtu.be/dGZznvp7Pjo

My guess would be there is a space before the Youtube URL and thus it doesn't detect it as an absolute URL.

Yes there was a space in front of the URL. However, removing it did not resolve the issue. Error message is still there and the video still is not showing up.

www.covenantsuncitywest.org/sermons/sermons

The URL looks now fine. You may want to check the "Sermons" menu item now and see if there is a filter set (under "Advanced" -> "Type Filter".
Also make sure you don't have a page cache active. Delete any cached pages to be sure you don't see an old page.

If all doesn't work, you may want to test with a different player (eg Mediaelement) or use the full Youtube URL ( www.youtube.com/watch?v=dGZznvp7Pjo ) instead of the shortened one ( youtu.be/dGZznvp7Pjo )

No filters. Changed URL to full YT one. Cleared cache and tried a different browser. Also tried in Incognito mode. Still showing the error and no video showing.

I downloaded Mediaelement, but don't know how I install it.

You download the package from here: www.sermonspeaker.net/download/player-me...iaelement-1-0-1.html

Then install it like any other Joomla extension

Then go to the Joomla Plugin Manager and enable the "SermonSpeaker - MediaElement.js" plugin and disable all other plugins of type "sermonspeaker".

In the SermonSpeaker options -> "Player" tab, make sure the parameter "Player" is set to "- Use Plugin -".
