Are you saying that only half the "edit" page is loading? Is the "Save" button missing at the bottom? Is this for all the names or just some?
The edit page is ok, its when I save the information or go to another person that half the bottom page does not appear, it does eventually but very annoying as I have the deluxe site. I am in the process of transferring my tree via GEDCOM, to ancestry and if things do not improve by the time I need to renew my membership I will delete the tree which I would do reluctantly as I have been a member for many years and up to now been very happy with tribalpages.
