HTML5 placeholder image not loading

[heberbrandao]

Hello team,
I am currently working with HTML5 videos on my projects, and suddenly the placeholder images are no longer loading on Chrome/Safari.
I checked all the documentation, compared the source code from all my projects, everything seems to be fine.
Has anyone also faced this issue?
Thanks in advance

Hello @mariusjopen ,
this is the website, and more specifically the page.

Somehow the placeholder image does not open until refreshed. http://andreszardenings.com/venla

Dear @heberbrandao
do you use any plugins?

All the best!
