We just upgraded an instance from 8.0.1 to 10.0.3 and we are now testing the instance. All seems to be good but for some reason when we open a contact or a lead we do get multiple messages stating that there are multiple links found for relationship x within module y. For instance:
"Multiple links found for relationship contact_tasks within module Contacts"
I checked to see if there are any definitions in the custom directory for this specific relationship. The only mention of this relationship can be found in the modules/Contacts/vardefs.php which is the place I would expect it to be. After removal of the cache, quick repair & rebuild and even a repair relationships I couldn't get these messages away. Can someone point me in the right direction where to watch?
