    I wanted to change the template on our website http://www.halcyonadventure.com/ to twentyten.

    It only seems to work with 3.0 so I decided to upgrade. I'm new to wordpress (someone else set up this site) so I'm panicking now I've completely stuffed it up and haven't a clue how to put it right.

    I just get blank screens. The source code is just:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
    <META content="text/html; charset=utf-8" http-equiv=Content-Type></HEAD>

    and it's the same on /wp-admin/ and /wp-content/ pages.

    How can i revert back to 2.9.2 please?

  2. Try resettings your plugins. If that resolves the issue, reactivate each one individually until you find the cause.

    Thanks macmanx - just hope I don't completely stuff up the database while I'm doing it!

    its always nice to have a backup of your DB just in case, but manipulating files, etc should never have an effect on your DB. If @macmanx's suggestion doesn't work, the next thing to try is to rename/delete your active theme (if you are using a custom one) so that your install will revert to the new twentyten theme. And finally if neither of those work, reuploading the contents of the wp-admin and wp-includes folders often works.

    It seems following these 3 troubleshooting steps fixes most problems I've seen on upgrades gone bad
