Hey Thanks for the post.
I’ve downloaded the plugin and run through the repair and optimize and this didn’t help resolve. I manually scanned through the DB using phpMyAdmin-3.0.1 but I couldn’t find anything obvious. I would try and recreate the DB and import across the posts but don’t have any experience with this and presume it isn’t straight forward.
I’ve restored a backup DB but this has the same issue, perhaps the problem may be with the hosting company? I can’t think of any other aspects which may affect the display.
