Youtube videos not showing

Hello guys,

I have a problem displaying youtube videos on my very recently self-hosted blog at https://www.mrpalsmy.com with the Vblog page https://www.mrpalsmy.com/?page_id=6330

I have no such situation as the above on my wordpress.com blog I still wish to maintain at https://mrpaslmy.wordpress.com

The videos are embedded in a grid with text below each one of them.

Kindly advise. Thank You.
