Export that category, and then import it.

This just happened to me.

how export cat? need backup?
May this depends:
In https://polisphotos.com(primary) hosting i changed primary domain polisphotos.com to something else by error, and after bring it back, has anything this has to do with this problem?

Try these steps:
1. Deactivate all plugins
2. Revert to the WordPress default theme to see if the problem is related to your theme.
3. Make sure that your plugins are updated and activate them one by one to see if the problems are caused by any plugins.

Go to tools, and choose export.
Export that particular category or date, or whatever is closest to the post you’ve lost.
Then import. It’s also in tools.
You may need to install the wordpress importer, but it’s simple enough.

Good luck.

I exported as xml file, all now to import must delete first after impoort or not required? db backup better done prior this?

did you change permalinks?

where this setting located?

I got the same problem but i go to the post and click on update and all just went fine….. You can edit/change the link of the post below the title maybe it works…

did not work

I got:

Import WordPress
Sorry, there has been an error.
File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini or by post_max_size being defined as smaller than upload_max_filesize in php.ini.

may try the update of whole wordpress, instead?

problem fixed: went: settings > permalinks and changed mode of permanent links… thks for all
