No items visible on site after upgrading to 4.0.1

Hello, I have a site that I’ve just upgraded to 4.0.1. The public site won’t display any item sets or search results, although I can navigate directly to items with item/id. Following a link to an item set or navigating to /item-set/id or performing a search or an advanced search all bring up “0 results”. All the item sets and items show up correctly in the admin site.

I have all modules deactivated and have also tried removing them from the file system but the problem persists. I am using the default theme. As far as I can tell this isn’t producing an error.

Thanks,
Leah

Check the “Resources” section of the admin for your site. The way items get assigned to sites changed in version 3.0. You can use the Resources section to make changes in bulk to what’s attached to the site, or set those attachments one-by-one in the Sites tab for each item.
