I've migrated this site from j2store to Hikashop and am now getting an error message on the product category list saying: you are not authorised to view this resource. This happens only when I'm logged in as a user who is not part of the Joomla group "reseller" or "superadministrator". If I'm one of those two, or a guest, that message doesn't appear. This message also goes away when I disable the System - JomSocial Redirect plugin. However, I would prefer to keep using that plugin to collect more user information on registration.
