I recently did a fresh install of MediaWiki 1.4.10 on a new server and I'm importing text from my old install. While it worked fine at first, it suddenly stopped letting me save edits to pages. Instead I seem to be stuck in preview! I see I'm not the first person to have this problem:

But I can't figure out if there is any solution. Someone said something about creating a "sessions" directory, but creating such a directory in wiki folder didn'ty seem to make a difference.
If your hosting provider is using a server farm with multiple hosts, the default PHP session configuration may be storing data on a local drive which breaks things.
Try checking the directions for running on Sourceforge, which has a similar issue: http://meta.wikimedia.org/wiki/Sourceforge#Sessions
Just making a directory isn't enough; you'll have to configure it, as described there.
