Can not access deep category and product links - url shortened

Question

when I try to access some deep category I am alwyas redirected to link of parent category.

for example i try access store.com/category/subcategory/subcategory2/subcategory3/subcategory4 but i am redirected to store.com/category/subcategory/subcategory2/subcategory3

same with deep product url store.com/category/subcategory/subcategory2/subcategory3/product also redirects to store.com/category/subcategory/subcategory2/subcategory3

i am using nginx server. but i discovered that this redirecting happening in magento, not with server rewrites. can someone point me where should i start search?

i am using CE 1.9.2.1 with few plugins and porto theme

Answer 1

finaly found answer. it is caused by MKleine_LanguageRoutes module. when this is disabled, deeper links work again.
