Blank Blog Page - Blog post summaries not appearing on blog page after Wordpress migration - SOLVED

I imported a client's blog from Wordpress and all the posts came across, however the post summaries (thumbnails, excerpts, etc) did not appear on the main blog page. I could see the list of posts in the editor on the left but they weren't appearing on the blog page itself. I had migrated blogs from Wordpress several times in the past and had never encountered this issue before. I've attached a screenshot of the problem.

Thanks to Faye S from Squarespace Customer Care, I solved it by creating a new blog page and moving the posts to the new blog page. The new blog page populated as normal with the blog post summaries (thumbnails, excerpts, etc)

I used this support page to learn how to move collections - Move Collection Items (first create new blog page)

Hopefully this helps others who encounter the same problem. 🙂

Hi,
I just imported a blog from wordpress, and it didn't import the thumbnails at all.
