Can't see anything on my page "Tours"

Hello,
I Have 3 question:
1- I have just added two tours, but when i click on the page”Tours” can’t see any of them. Also when i click on the tour details “Read More”, the head title of the page show the title name of the tour. Check it with me please:

http://short-moroccotours.com/tours/marrakesh-to-marrakesh-through-desert

2- Why i can’t see the categories when i try to add new tour. there is “tour type” but no “Categories”
3- Also the tour list doesn’t show all tours.

Your assistance in this matter is greatly appreciated!
Thanks everybody
