selarsen, I'd like to try fixing this issue. If you could please make an export of your database and post it somewhere, then send me a link to that backup file in a message through http://technobabbl.es/contact/, I'll get that data into my test site and hack on it when I get some free time.
Note that the version of 188.8.131.52 you have isn't final, so depending on how you updated LightWord this time you might have to change your method and do this instead. (WP has some good safeguards, but sometimes they just get in the way.)
Please do remind me of both issues discussed here (the sidebar and the menu failure), since it might be a few weeks before I get to this project. Also, it couldn't hurt to have screenshots of a page that works and a page that's broken, for my reference while I'm trying to fix it.
Thanks for your help. I'm sure this one will be fixed in the end. :)
