Image block error

Dear all,

My site is a self-hosted WordPress blog and since about 2 weeks I’ve been noticing issues with my image blocks. Every time I add an image block in a post that is more wide than it is high (for example 800x300px), once I publish the post there is a space added underneath the image that is roughly the same size as the width.

This only happens once the post is published, because I see no issue in the editor nor in the preview. And it also does not happen for images where the height is bigger than the width nor for square images. It also happened for all of my older posts that were perfectly fine up until a few weeks ago.

Thanks to another forum post, I found out it was related to the Social Snap plugin, because as soon as I deactivated this, my images displayed correctly again.

Would anyone be able to look into this please, so I can active this plugin again without errors?

Thanks in advance!
