Images disconnected from subsites

The URL given is only a sample post. None of the images in the subsites show up in the image library or the posts since a database update about 9 months ago. (I asked for help with other issues back then. The image library shows a bunch of grey boxes with the image info, even the option to “edit.” But there’s no real image to edit.

The images show up when the exact URL is typed into the browser. For instance, the missing image in the sample post shows up at https://ssnet.org/wp-content/blogs.dir/12/files/2013/05/International_Date_Line2.jpg That’s because the Network Admin settings for this site indicate that the fileupload_url should be
https://ssnet.org/public_html/wp-content/blogs.dir/12/files

But WordPress looks for the file at https://sabbathissues.org/files/2013/05/International_Date_Line2.jpg

That is supposed to work because the upload_url_path is set to https://sabbathissues.org/files, but it doesn’t. For good measure, I’ve also tried uploading the image files to the following directories and specified them in the Network Admin settings for the site:
https://ssnet.org/public_html/wp-content/uploads/sites/12/files/2013/05/International_Date_Line2.jpg That URL renders the file URL on a black background! (That destination is currently not specified as the upload_url_path but specifying it as such generates precisely the same results.)

I also uploaded the images into the https://ssnet.org/sabbathissues directory, and the URL https://ssnet.org/sabbathissues/files/2013/05/International_Date_Line2.jpg. And the URL renders just fine, but the blog page does not fetch the image

Another problem is this: While all the posts how up as they are supposed to on the public site, they do can not be “edited.” “Quick edit” works, but “edit” only renders a blank page.

Below is a copy of my .htaccess file.

I need help fixing the disconnect between the existing image files and the image library and posts. I would also like to see editable posts.

Thanks much!
