[CR 343624] After an upgrade from EP 5.x to EP 6.0, users have the option of enabling page group support by setting the global.properties.xml attribute page.groups to TRUE. Once this is done, any page groups that existed in EP 5.x are interpreted as a Default page group, rendering them unmodifiable.
Workaround: open an isql session to the database server hosting your portal database and execute the following commands:
use portaldatabase go update tab_sets set description=‘C’ go
where description is null, or description =‘default’.
If you are not sure where your portaldatabase is hosted, consult your global.properties.xml file.
