I've been using YARRP (now on version 4.0.6) for months on two sites, one is a store for US, the other a store for Europe, but both are identical in every way.
On one of the sites the "Relatedness" option for "Titles" has stopped working. On the other site it still works fine. I tried clearing the YARRP cache in the Php MyAdmin for the site that's not working properly but that didn't help.
Any idea why the "Relatedness" option for "Titles" would stop working on one site, but still work perfectly on another site that's
exactly the same?
Any help would be appreciated.
Thanks for a great plugin!
