Hi,
When I import the nb-NO language file, all the EMAIL_..._SUBJECT fields with line feed in the string give an error when sending email. After removing line feeds in all the SUBJECT fields, it works flawless. This applies to DNN 4.x.

If I try to export a fixed language file there is no line feeds in it so this is probably error with this spesific language file, even thought I suspect the language author is exporting from 3.x (and not from 4.x)... it could be something funny going on between the versions.

This will produce an error:
<data name="EMAIL_PASSWORD_REMINDER_SUBJECT.Text">
    <value>Passord til [Portal:PortalName]
    </value>
</data>

This don't:
<data name="EMAIL_PASSWORD_REMINDER_SUBJECT.Text">
    <value>Passord til [Portal:PortalName]</value>
</data>

I guess I could fix this minor bug by trimming and removing the line feeds in the subject-fields before calling SendMail. Thought you'd like to know :)

With kind regards,
Bonavox
