flojnel on "Import tool not working"

I've been using the export/import tools to export from a site that has new content to be imported into several other sites. It has worked well so far, but after the last WP updates, I can't get it to work.

The export is of multiple different types of content - pages, posts, media, menus, etc. Now it tells me it's importing, but nothing happens.

I also have a WPMU plugin for copying posts from one site to another and that isn't working. Their forum says they're working on the issue.

Anyone run into this and have any ideas?
