Hello and thanks for the great support.
After a few months using Viper's Video Quicktags, all the youtube URL's embedded in my website worked like this:
I have recently updated wordpress and also updated Viper's. After that, Viper's not detecting my old Youtube URL's and I have to insert them like this:
In the other format I get an error message "Invalid URL"
I don't care using a different type of URL from now on but I have hundred of videos already embedded that won't be viewable with the new version of Viper's.
So I had to downgrade and went back to the older version of Viper's.
Is there any solution to use new Viper´s and it detect my old Youtube URL's?
