Hi,
The wordpress is auto cropping the images. You use a rectangle on the archive page while using square on the homepage. I recommend you to edit the photo according to the format. Or you can go to appearance > customize > blog > change it to list format for all formats.
Thanks
Hi,
Please go to dashboard > settings > media > uncheck “Crop thumbnail to exact dimensions (normally thumbnails are proportional)” and save it.
If you still have the issue, i will forward this topic to our wordpress developer.
Thanks
