SharePoint 2010: Getting Publishing template working
Note: this post is only relevant for people running the SharePoint 2010 Technology Preview.
When I create a new site based on the Publishing Portal template you get a .../Pages/Default.aspx page with an error on it. The error seems to be generated by a ContentByQuery web part (the only web part) on the page. Add ?contents=1 to the url (…/Pages/Default.aspx?contents=1):
Check Out the page, remove the web part (Delete, not Close), and your page starts working again.
