Website having more than 135 categories/ subcategories.
It is working fine with existing subcategory page but If I create any new subcategory or change slug for already existing subcategory(which is working fine), it redirects to 404 page.
Ex: http://overseasattractions.com/pacific/australia/melbourne/ is working fine.
but if i try to change slug for ‘melbourne’ it redirects to 404 page.
Ex: http://overseasattractions.com/pacific/australia/adelaide/
This is the new created subcategory under the same parent category but it redirects to 404.
Please help as I am not much aware or wordpress and such redirections.
If you Change permalink on site then must update all category with new permalink then you are able to display category and work properly on site.
otherwise you go with existing permalink on site and add new category or sub category.
