Try resetting your permalinks by going to Settings > Permalinks > Save.
i bit the bullet and deleted all the pages. Started a new page without the ability to add comment i9.e. a static page. It works.
Added a second page with the ability to add comments and ping-backs etc.
No parent, sidebar template, Order 0., Pressed Update. Then View page – 404 error!!
There is a menu item on the first page to the second.
It appears that the second page is not uploading to the server.

Do you have a link to your site? What theme are you using?
When you deactivate all plug-ins do you still have issues?
If you switch to the default Twenty Eleven theme temporarily, do you have the same problem?
Site is http://www.canadianrallyo.ca/wordpress.
Only plugin is Akismet – now deactivated.
Using the default Twenty Eleven thems.
Same problem
Suggestions: empty your trash of all posts and pages.
Now create a page that has a name other than “novice”. Looks like you have both a deleted page as well as a category with the same slug (“novice”) – that could be causing conflicts.
Double check your custom permalink structure as your category link is really messed up:
http://www.canadianrallyo.ca/wordpress/:%20/category/levels/novice/
Choose one of the standard permalink options rather than creating your own (if you have) and reset permalinks.
Merci
Thank you
