The popular and free Helferlein form has a reported bug that shows an error message when attempting to get into the module settings. The work around is reported on the following link:

Specifically, the instructions state to copty the following SQL code and paste it into the SQL page in the host menu.

INSERT INTO {databaseOwner}{object Qualifier}PortalSettings(PortalID, SettingName, SettingValue)
VALUES(portalID, 'Security_EmailValidation', '\b[a-zA-Z0-9._%\-+'']+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,4}\b')

I found that I had to actually edit the database in MS< SQL Server Management Studio and enter the missing record myself.

It did solve the problem.
