I am unable to access my manage categories option in my magento admin panel. When i click on the manage categories ,it show that page does not exist.
It redirects to my old website url of 404 not found page.
I copied new adminhtml of magento in it, but still this error is showing up. When I open a product, here when I open manage products , then go to edit of product, after the product page is opened. In product page,There is categories option tab ,here the all categories are displaying.
I searched on google but didn't get any specific answer to this problem. Should I have to make any change in database to view manage categories page properly.
