Auction doesn't work

[Krapan]

Hey, don't really know what else can i do. So auction barely works for me. It finds items only if i don't chose any categories, like just press search button and nothing more. Sometimes even this way it doesn't find anything. I tried to install Shinies auc addon. It helped for like a day, and then after it didn't work again. I don't know what can i do in order to fix this problem, nor didn't i find anything on forums about this one. And i was not the only one having this sort of problem with auction.
