Post's Featured Image is streched

If the theme was installed after the images were upload then you’ll need to regenerate the thumbnails.

I recommend using the Regenerate Thumbnails plugin.

If that does not help please provide the site link so that I can take a look to be able to advise you better.

hello, the Regenerate Thumbnails plugin didn’t help. Here’s the link to my website’s blog: https://www.seabookings.com/blog/

My blog’s only post has the featured image distorted when go inside the post. The image doesn’t seem to distort on every screen, only some, don’t know why.

I am having a similar problem. Several square featured images on posts are showing up fine in the header, but distorted on the actual post.

For example, on this post, the featured image is distorted (site is in development, hence dummy text):

But on the main page, the header image is fine (pic is still distorted in blog roll):

Could you give more details on the distortion?

Viewing on FF, Chrome and IE10/11 the images seem fine to me on both https://www.seabookings.com/blog/ and https://www.stonedcrowpress.com/
