YouTube iframe http and not https

Hi,

I’m ising your plugin on a site of mine. The link to my YouTube video says https://, but when opening in lightbox and looking in generated iframe it says http://, wich breaks the link. What to do?

Please see right above the footer and “See the film about Sky”: https://skyhotelapartments.se/?lang=en

Thank you,
Daniel
