I'm using version 3.0.3, but that apparently isn't an option.
I tried using the LJ importer tonight on my Livejournal account, which houses posts from 2000-2010. It managed to fetch posts from 2003-2006 (I've no idea why it didn't start at the beginning) before dropping dead and giving me this message:
Fatal error: Call to a member function step1() on a non-object in /home1/(domain)/public_html/(name)/ljposts/wp-content/plugins/livejournal-importer/livejournal-importer.php on line 22
Any ideas how to fix this?
