[Plugin: Custom Contact Forms] translation

There seems to be some error on the code, because i am not able to translate the default_form_error_header (You filled out the form incorrectly). I have already translated the .po file and in what form submission errors are concern that′s the only sentence left to translate.

I have check the code and this part is not on the language vars. I am not a coder, so please someone….

Thanks
