Category and Manufacturer Navigation are not working on our store.

Cause of the problem:

The "currentCategoryId" is the parameter passed to invoke the CategoryNavigation ViewComponent and is always 0 with nopAccelerate Plus because the controller name is not same as ‘catalog’ since it is overwritten by the nopAccelerate Plus plugin.


You can change the Controller Name in _ColumnsTwo.cshtml page of NopCommerce,When you are using NopAccelerate Catalog Plugin.
Replace catalog Controller with NopAcceleratePlusWebCatalog in .cshtml to Load CategoryNavigation & Manufacturer Navigation.
