I have 7 categories of my works to show in portfolio. I made 7 portfolio categories and 7 page to show them. For each portfolio page I set only one category. All are set the same (differing only in the categories).
But only 2 works fine: http://www.suder.nazwa.pl/pawelsuder/2011/reportaz/ (show portfolio items from only 1 category)
The rest of them display all items from all categories in one column, but there is 3 set http://www.suder.nazwa.pl/pawelsuder/2011/przemysl/
