I was using my feature images’ dimensions perfectly with Big Grid 3, but after 9.2 update thumbs are not showing properly.

Thanks for help

Add:
My big grid was look like this one (big thumbnail is using 16:9 featured image): https://demo.tagdiv.com/newspaper/category/tagdiv-lifestyle/tagdiv-travel/
If i’m not wrong, we don’t have to use 4:3 images in featured images for Big Grid 3.

Same problem in 9.2.

Thanks for reply.
I regenerated all thumbnails but problem didn’t solved and i tried flex but i don’t like results.
Is there any solution for my problem beside regenerating thumbs or changing grid style?
Because i was use it without any problem since 9.2 update and as you see example in my second message, 16:9 images can be use with Big Grid 3 if i’m correct

Hello again, for now i solved my problem with using slightly bigger picture resolutions.
Thanks for help.

Hello,
I’m experiencing the same problem. After the update to 9.2, all of the thumbs disappeared. Changed to another gride style but it did not help. The regeneration of the thumbnails did not help either. It is not an option for me to change the resolution of the images because I have too many of them. Please help

Hi Calin, please stop giving people generic answer to regenerate thumbnails as thats not solo solution.

@Everyone, You have to go to Setttings > Media and increase your image sizes. You might also go to Newwspaper > Block settings > Thumbs on modules/blocks to increase sizes, but I dont think it will be necessary in most cases.

After that you go and regenerate thumbnails (use plugin)

Thats solution
