error with Email [GH] action: Language string failed to load

Dear all,
i successfull install Email [GH] action, in order to simply attach uploaded files to the email when is compiled a forms.

All works correctly.

After this action, happens a strange thing. When I click to "submit button" on frontend, chronoform show "Language string failed to load: invalid_address:" before to show "thank you for ......."
I have an Italian Joomla 1.7 installation.

How I can remove this error?

Thank you.

Hi [email]molteni@divis.it[/email] ,

This seems to be a Joomla! bug that shows up if the From email address in your *Site* email configuration does not match the site domain. Please search here on the error message for a couple of other threads on this topic.

Thank you Bob,
In the forum I find, try and apply this workaround:
Edit the following file: libraries/phpmailer/phpmailer.php

from this
if(isset($this->language[$key])) {
return $this->language[$key];
} else {
return 'Language string failed to load: ' . $key;
}
to this:
/* if(isset($this->language[$key])) {
return $this->language[$key];
} else {
return 'Language string failed to load: ' . $key;
} */

It works!
