@sb_cole Unfortunately I haven’t found at great solution yet. I kind of think it has something to do with the WordPress Importer and the latest version of 3.3 as well. :\
I am trying to import from one WordPress 3.3 blog to another. My file already has <wp:wxr_version>1.1</wp:wxr_version> in it. Anyone else having issues using the importer with WordPress 3.3?
