Broken lightbox link

Hi Vladimir,

I have updated to 4.1.4 today. Yesterday I embedded some buttons linking to a YouTube video embedded as an iframe in a lightbox. See the buttons labeled “Eu Vou Ser Mais Eu”, “La Solitudine”, “Sofrer de Amor” here:

It worked perfectly. After the update, strangely, the buttons link to the main page. The shortcode I’m using for the first button is the following:

[lightbox src=”http://www.youtube.com/watch?v=Dt7x6LyyOIQ”%5D%5Bbutton style=”soft” background=”#2B38C4″ wide=”yes” size=”4″] Eu Vou Ser Mais Eu [/button][/lightbox]
