The content management page at /admin/content reports that my Backdrop 1.20.0 site has no content, even though it does have content appearing on the front page. The dashboard reports that content exists on my site. Any suggestions on how to troubleshoot this issue? I have tried clearing the cache, running cron and database updates, manually truncating the cache tables in the database, and disabling contributed modules.
Can you reproduce this on another site or at least provide a screenshot, so we can be certain of what you are looking at and/or if there are any visible clues regarding what might be happening?
I was able to resolve the issue by removing the "Has new content" exposed filter from the view. Apparently this filter hides all content on my site, whether it is checked or unchecked.
