Ok, My Arabic is not very good!...but I managed to navigate around. I'm a little unsure why this is happening. I guess, the fact you have some products and categories in the system means it did work before??.....if so at which point did it stop working?.....did you remove a category the products where linked too?
I think my first approach would be to export all products and see what's in there, then clear the store from "Admin>delete all content" and then try re-inputting the categories and products manually to see if it starts working. Maybe even try the importing the export file you made before clearing the store.
If does look like there is some kind of data issue with your store, the trick is to find out what went wrong!
