Maybe a check or option that looks of a category alias exits ? Last edit: 11 years 4 months ago by [davey](/forum/user/37720-davey "View davey's Profile").

If however the ids are removed, then the system can only base itself on the alias and thus it has to be unique if you want to access the different elements. We've actually added such check already for HikaShop 2.5.0 Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzI2LXByb2R1Y3QtY2F0ZWdvcnktZGlzcGxheS84Nzc2OTMtY2F0ZWdvcnktaGFzLXRvLWJlLXVuaXF1ZT90bXBsPW1hcmtkb3du) or [Create an account](/component/users/registration?Itemid=101) to join the conversation.
