You use 3rd party analytics software to track information about the NetCommunity site. Your software is reporting duplicate NetCommunity pages. It may show duplicate pages with a / on the end. For example, one page shows www.netcommunitysite.com and the other shows www.netcommunitysite.com/. You want to know if there is a way to remove the duplicate page from NetCommunity.
The NetCommunity product itself does not produce duplicate pages with a trailing /. This is the result of how the analytics software is interpreting the NetCommunity pages. Blackbaud Support cannot troubleshoot 3rd party software.
