I got this error and found this info about it in FAQ:
If you've configured FormMail, and whenever you submit a form you receive an alert message like this:
The following error occurred in FormMail :no_valid_recipients **********Error=The form has an internal error - no valid recipients were specified.then you've either made an error in configuring FormMail or in setting the "recipients" (note the "s") hidden field in your HTML form.
how do I go about reconfiguring the file? thanks...
