A lot of us dread to upgrade our software because of messages just like this

your attempt to edit this post has failed

Most often it is due to an incompatibility with a plugin. It appears that is the problem here as well. The very popular plugin Twitter Tools is the most likely culprit. If you see this message when you first try to save or publish a post in WordPress 2.9, the first thing you want to do is to de-activate the Twitter Tools plugin. That cleared up the problem for me.

A few people have reported this error with the All in One SEO plugin as well but it has not caused a problem on any of the 12 blogs that I manage. If you continue to have problems, deactivate ALL of your plugins. Then try to save a new post. If that works, reactivate your plug-ins until you find the source of your trouble.

What happened to WordPress 2.9 checking for plug-in compatibility? Well WordPress 2.9 does and lots of people have had no problems with the Twitter Tool plug in on their WordPress 2.9 blog. Alex King, the developer of Twitter Tools is hard with the WordPress developers trying to isolate the cause. I can tell you that this is one of the most difficult times to debug, when something works for most set ups but not for a small group of others.

Should I upgrade?

WordPress 2.9 is a feature upgrade. It is not a security upgrade, which should ALWAYS be installed as soon as possible. You could wait a week or so for some of the dust to settle before upgrading. Many people will make that choice if it is a feature vs security upgrade, as it is in this situation. You can wait and take one of the blogging classes that start after the new year to have my assistance and guidance when you upgrade.
