Problems with Nevspaper

Hello.
An excellent and very necessary plugin.
Unfortunately, there are problems with the popular theme Nevspaper.
On the main page of the site (rugde.ru), all links to articles do not have a category at all (eg http://rugde.ru//domashnie-zhivotnye-v-zhizni-rebenka.html).
Such links do not work.
At the same time, On other pages of the site contains the correct links.
(eg http://rugde.ru/stati).
Can you help me fix this?
