Multishop displaying category where it shouldn't

[TourisT]

Hi,

 

I have a category structure like:

+ Home

- A

- B

- C

 

I have a shop structure like:

+ group:default

- 1

- 2

- 3

+ group:other

- 4

 

Shop 1 should contain all products from A and B (only!)

Shop 2 is supposed to show only A and its subcategories (if any)

Shop 3 is supposed to show only B and its subcats (if any)

Shop 4 is supposed to show only C and its subcats (if any)

 

Problem: When I go on the back office to:

Catalog -> Categories

with "multishop configuration for" drop down:

on Shop 2

-> I get "The page isn't redirecting properly"

on Shop 1 or 3

-> it's working properly!

 

Also if I edit a category to not show for a specific shop, it sometimes fails...

 

Am I missing something? Does somebody have a good tutorial (ideally video) for multishops?

 

Thanks,
