I'm still having this issue also, I even have issues where MOST of my uploaded images (in a gallery on a blog post) appear to be stretched out in addition to not being able to upload a banner photo. I also can't upload a custom thumbnail to a video.
 
Have you heard of any fix for this as of yet? Thanks!

This is the reply I got, and YE, their "fix" option works.
 
Thanks for reaching out, I can lend a hand here.
 
I understand you have noted the Masonry style Blog Page display for your "Portfolio" Blog Page is currently displaying your recently uploaded thumbnail imagery in incorrect aspect ratios, though they appear correctly configured in your Homepage's Summary Block. I would be happy to assist you with that!
 
Thank you for reporting this behavior. We’ve noted this for our Design and Engineering teams to review, and they’ll use this feedback when implementing fixes and improvements in future releases. I see that we've received a couple of other reports of the same behavior from other users, so our team is looking into the matter now!
 
For the time being, this issue can be resolved by opening uploaded images in the built-in image editing function within the site, then saving immediately. We have details here on our support site regarding the process of opening an image in our built-in image editing function:
 
Editing images on your site
 
You don't need to make any changes, just open the image in the editor, then select Save! This restores the image's use of its original Aspect Ratio.
 
I want to set the expectation that this is an alternative solution you can use temporarily, rather than a permanent fix for the exact issue. We've found that this issue is less likely to appear with images optimized for display on our platform, with file sizes of less than 500MB. Additionally, the issue is more likely to occur if your images' settings don't fully match our guidelines, including the sRGB color profile, which is often the cause of this issue. You can read about image optimization suggestions like this here on our support site:

Please keep in mind that there are many moving parts we need to address before any changes are made, and we can't guarantee changes to this behavior in the immediate future. With this in mind, opening your Blog Posts' settings individually, selecting the "Edit" function associated with the thumbnail image, and saving without making changes in place is the best way to resolve this error for the time being. That said, all feedback is reviewed and your continued input is always encouraged.
 
Thank you again for reporting this. If you come across any other unusual behavior in the future, please let us know.
 
Kind regards,
River Z.

Well, I just emailed customer support. The blogs I made weren't duplicated from older ones, I always make a "new post." Hopefully they can help! I don't have any CSS or JS running that would interfere with anything either.
 
Thanks for your reply! 

Squarespace recently made changes to the Blog Post UI and to the way 'Featured Images' (previously known as 'Thumbnail Images' 🙂) are handled so some invalid data is possibly being carried over. I can see that your old posts have an data-parent-ratio of 0.7 whereas the new posts have a ratio of 1.5, and whilst this isn't something that you can control, it is why they don't display correctly.
If you created the new posts by duplicating an existing post then you may want to try creating a completely new post and add a portrait Featured Image to see if the new post displays correctly. f it doesn't, I recommend that you contact Customer Care for this one as it looks like a bug and this will be difficult to troubleshoot further without access to the site configuration. 
Please post back to let us know how you get on.
