Help, pages dissapear :s

I made so much pages for each 'first' button on my menu's.
But now i click on it, and the page is gone.. (very strange)

1 of the pages are http://www.busimatch.com/page/titelmybusimatch
When i look in the builder, the page exist.. i see it.

But when i click on it, or copy paste the link.

I see nothing.. what can be the problem pleaseeeee? 

go to the page builder.  bring up one of the pages you can not see.  Click on the review link and let Dolphin open up the page in a new tab.  Check the address/URL that you see in the browser address bar with the one that is on your menu and see if they match.

ok, thank you, it is ok now ;-)
