I'm using Wordpress and recently upgraded to CiviCRM version 4.6.3. Since I have the editor for individual contacts has ceased to save changes. When viewing an individual contact, I can edit fields using the in-line editors, but when I click the "EDIT" button and edit from the contact editor and click "SAVE", I get a message saying the contact has been updated but the new information is nowhere to be found! The editor does work for households and organizations though.
I did duplicate this on the demo site.
