So, I was adding people to my family tree. My sister then contacted me and told me that something was wrong, a person was listed as having a different dad than his siblings so I tried to fix it. Everytime I try to I get this message.
A communication error has occured while saving the update.
Please click Retry to try again.
Every single time I try to update this person, to delete him and this un-named father, it won't work.
