Can't insert anymore youtube videos on product page

[radu_cmr]

Hi,

I have some products on my store (catalogue mode) for which I have inserted also embed movies from youtube. Unfortunately this is not possible anymore even I didn't modified/update nothing to my website.. only maybe youtube made updates. 

I can't do any modifications to products that have movies on Description page because when I try to save I get the message "Invalid description field"

I'm using prestashop 1.7.6.7.

Did you face such problems, any ideea how could I solve the problem?

One example of a product for which I already have a movie, but can't modify it anymore without deleting the movie
