We've been using this plugin for over 6 months now with great success, and we used to get a lot of traffic from other websites.
However we've just noticed that we're not receiving any traffic from other sites anymore on two separate sites that we run. Previously we had 4 related posts show beneath the body of our article, and the 4th one was usually an external site.
This is not happening anymore and the "number of visits received" from external sites is showing as 0 in the admin.
Whats going on?
