I am right there with seagee69. I have been fighting this battle with the scripts error for the past few days and nothing I do seems to fix it.
I have opened Ancestry.com from my browser and do not get the scripts error. It is only when I click on the little leaf for more information and connect to the internet that I receive this scripts message.
I just recently upgraded to IE10 day before yesterday (16 Mar) and thought perhaps this might fix the problem but it didn't.
I have never had this problem before and quite frankly it is very frustrating. If it just happened once, no problem but every time I go from one Public Tree and back it happens.
Any other suggestions?
