I’ve just encountered the same problem. Here is how I managed to resolve it.
Here is how to get your post visible again.
First of all, you will need a SQLite Database editor like this one : https://sqlitebrowser.org/dl/.
Then :
- Open your Publii site directory
For me : “Documents > Publii > Sites”
- Find the db.sqlite file into the “input” directory
- Edit the SQLite database with SQLiteBrowser
- Browse the “posts” table data and find the posts without title, slug or status
- The wp_import tool did not save anything in these fields for blog posts of custom type “quote”
- For these records, you can
- delete the rows
- edit the rows and type in a title, a unique slug and define a status (published or draft)
Then you need publii to reload the database : this can be done by changing the site you are editing or by closing and reopening the ublii application.
And… voilà !
I hope this wil do the trick for you as well.
I think, wp_import does not handle WordPress custom post types.
