I have a problem when I am posting new posts in WordPress. Ever since I upgraded to WordPress 2.9, whenever I try to add a new post it fails. Luckily I had auto-save going. I then would go in and edit the post and publish it and everything would work fine.
It just got quite frustrating doing this every single time I posted.
I didn't have any luck on the WP Forums, but found a great post on ghacks.net about the issue. Wordpress: Your attempt to edit this post has failed described my problem to the letter and had a possible fix. I did the fix and I am not having any problems right now. It works great.
The only issue now is that auto-save is disabled.
I hope someone can find the fix and I can turn autosave back on.
