I know it's your weekend & I'm not trying to rush you
but I think I figured out the problem. Although I migrated all of the Joomla users from the previous site & imported all the EB tables, the posts are all assigned to Guest as the author. I've changed a few to the correct author & think I'll be able to edit now.
This has uncovered another problem, though - it won't let me use my previous bio permalink b/c it says it's already in use. How can I assign the permalinks that we were using previously so our incoming bio links won't be broken?
Thanks for your help!
