My pages keep disappearing from my blog nav bar. Every time I create a new page it is listed on the nav bar, but when I refresh the page the nav link is gone. The page remains at the correct URL but can't be found via the nav bar at all.
The URL is: http://wannaberollergirl.wordpress.com/ - and there should be one more page, called 'Stuff I like and use'. I've tried various shorter names etc and it still doesn't appear.
The theme is "Chunk" (free version) - I've tried other themes, which appear to work fine after I re-post the 'stuff...' page but when I revert back to "Chunk" it's broken again. Help very much appreciated!
The blog I need help with is wannaberollergirl.wordpress.com.
