Re: WordPress 3.0 – Page not Found
I’m not sure if this is a good solution, but it works for me until a fix is released. I installed the “Page Links To” plugin (http://txfx.net/code/wordpress/page-links-to/), created a new page called “Activity Temp”, and have it redirect to the Activity Stream. I set the temporary page as a child of another page so it doesn’t show up in the main navigation bar.
