If you get the error "Problem: Corrupt Data Exception Solution: Try Again" while adding a new users either to the list of allowed place creators or as Quickr administrators you should check:
- if you have a group called "LocalDomainServers" in the Domino directory of the Quickr server and
- if the Quickr server is included in this group
and correct this if this is not the case. Afterwards the error should no longer occur.
BTW: This should also fix the problem "Your password entries do not match. Please try again." while trying to create a new place.
