I changed screen layout in my Page editing window to single column. Now, it won't go back to 2 column. Note my screenshot: http://xenodesign.com/transfer/screenshot.png
This is a weird problem and it's not going away. Just updated to 3.1.1 the other day (don't know if that had any effect and I've re-installed once already). POSTS edit 2 column screen layout is OK. PAGE edit 2 column screen layout: not OK.
Can anyone help? Hope it's not a database issue.
Thanks!
