I've written a custom import script for a bespoke CMS to output Wordpress-friendly XML so I can use WP's importer plugin to import it. The format is exactly the same, as far as I can see, but the importer fails with some generic errors:
Failed to import tag. ...(x30) Failed to import post. ...(x7 thousand)
I've created a wordpress export file form the same site (with some dummy content) and this re-imports fine on a fresh install. I've made sure the XML is the same format as this, but I still get these errors.
What am I missing?
