It's the next page/previous page links on all the categories.
Now I got it. Thanks for the info.
There was an issue with the pager in the Nop Electronics theme that we had fixed in September. Would it be possible to double check the following:
1. Make sure that you use the latest version of the Nop Ajax Filters
2. Go to the administration of the filters and check for the "Pager Panel Integration Selector:" setting. It should have a value of ".product-grid, .product-list".
If possible can you let us know the package number you have used. It is in the package zip file name. For example NopAjaxFilters_3.6.805.17450.zip .
Looking forward to your reply.
