Cannot import WordPress json export to Ghost...
I just get a totally nonspecific error with no explanation. What am I doing wrong here?
In case this is still relevant to you, and since I had the same problem: It seems like some of the posts I tried to import contained data that tripped up Sqlite. So I switched my database to MySQL, using this tutorial: https://www.allaboutghost.com/migrating-ghost-installation-from-sqlite3-to-mysql/
Import still returned an error message after a while, but it turns out that all the posts were imported correctly this time.
Hope that helps!
