Posts are not displayed, but they are there?

the strange thing is that in the admin backend, the posts are “counted”, because it says that there are 4 posts. but they do not appear in the list.

when i change back to the default template (twentyfifteen) it works. so it must be an issue of zerif lite. can you help me where to look? i can read php code, so maybe i can find something…

Navigate to Admin > Settings > Permalink > Just set the default permalink like https://www.example.com/?p=12 to flush it. After that you can set the permalink to https://www.example.com/post-name/

thanks for the hint. however, i tried setting the permalinks settings back and forth multiple times. it still doesn’t work.. :/

Share the screenshots of Admin > Settings > Permalinks through https://droplr.com/.

If you any custom permalink plugin then uninstall it. Use only plain permalink option and check for issue.

I use the plugin Custom Post Type Permalinks. but when i disable it, the permalinks still dont work.

this was my mistake. i made another change a few weeks ago: i added a custom sortable column to the listings of a custom post type. this did affect the listing of my posts… i resolved it now by fixing the code, i added a few weeks ago.

sorry and thanks for helping!
