I am having the same issue. When I import from Squarespace, all the images are broken because they are referencing the domain of the Squarespace site. If I change the url of the image to the WordPress domain, I can see the image when I open it in the browser. However, changing the HTML of the WordPress post to the WordPress domain doesn’t display the image. I also have more than 600 blog posts which I am importing and it will take forever to manually remove each image and upload it into the WordPress media library. I have tried to use the Auto Upload Images plugins and several others but they have done nothing to fix the broken images when I do the bulk edit as the videos show me to do to activate the plugin. Please help as there has to be other users who have tried to import their Squarespace site into WordPress. Thank you!
