Portfolio items ‘disappeared’ ?

The last couple of days I was busy creating my Portfolio. Today I have added some more pages and added a ‘sort-order’ to them. The main Portfolio-page is okay now…but…..when I click on one of the photo’s to see more of that portfolio I get a page saying:

Page Not Found

Our apologies but the page you are looking for doesn’t excist. It seems that this is the result of:
– a wrong typed address
– an old link which doesn’t excist anymore

But as far as I can see the link is okay, but still the pages don’t show.

Even when I open a Portfolio-item and I press “Preview” it doesn’t find the page.

Anybody can help me with this?

[edit}
Solved, found this thread on this forum. Same applied to me.
