-NodeToOffsets Error:
OK, I see, that was not clear from the original report, the devil is in the details. I still am not able to reproduce the problem when using the Access pages manager that opens after the wizard is complete.
What is your OS?
What version of Dreamweaver are you using?
-Passwords
this also was not clear from the original report that the pages where using encryption. i will log a bug that the user update page should ignore the password entry if left blank.
