Before I imported my entries, cross-posting worked just fine. Suddenly my DW is having a heart attack every time I ask it to post to LJ for me, even though the little cross-post ticky boxes are clearly ticked.
I AM NOT HAPPY, DREAMWIDTH JOURNAL. ;-p
Note to self (and others like me): If you change your LJ password, you need to update your cross-post settings. Yes I'm a doofus.
