data:image/png;base64 no pictures

Hello, I use Wordpress and Newspaper Theme.

When I have a tabs with pictures I have only

Code (Text):

src="data:image/png;base64,iVBORw0KGgoAA

........, not URL of images.


in image class there is

Code (Text):

data-img-url="https... image.jpeg

and here I have a image.

Why it happen? Does something is missing in nginx config?

Please advise.

so it is nothing related to nginx? missing config?

 

Finally I have found a solution. It is a disable lazy load, a function on the theme.
This is a bug in the theme. Bug in in the newest version.

Hopefully it it not related to nginx

Thank you George
