Hi all, the thread that says this error AllVideos plugin is closed, so I say here the solution that I wrote in my blog:

Hello Jesus,

and thank you for sharing this.
You can get the latest version from here: github.com/joomlaworks/allvideos

dumb question. But I couldn't see a zip file (like a normal plug in for an update) on that link. How do I download and upload it? Is there an idiots guide?

On the right side there is a Clone or Downloab green button.
This will give you the zip file you want.
