i upgraded to the latest version of the plugin (some great features and updates, by the way) but it has done a terrible thing! Every single post's author was unassigned! Literally...of the 1500 posts published on my website, now none of them have an author. When looking at the lists of posts in the Dashboard, instead of listing an author it is just totally blank and lists nothing. What a pain! Why did this happen? Let me know if there is something that can be done.
