I needed to add a video to page/article in a Joomla! 3.8 site. I saw the JCE advertises as being able to do this with just a URL. I love the way WordPress embeds YouTube videos and hoped it would be the same experience. It wasn’t, but it wasn’t bad.
The first issue I had was my subscription was expired. That was a cheap fix. Less than 30 bucks and ready. After installing the Pro component I didn’t see where I could add video yet. I tried just the URL but that didn’t work. I solved my issue by adding the special toolbar in the JCE to the normal JCE toolbar. Here is a video of how to set this.
When a site gets moved the old indexed URLs lead to users linking to your site through their search may link to a page that no longer exists. Using Google’s Webmaster Tools you can eliminate old URLs, but in the mean time you can pretty quickly create your own 404 page not found error page. The article below is a great resource.
