In Magento 1.7 the message “Your inquiry was submitted and will be responded to as soon as possible. Thank you for contacting us.” that we get when the default contact us is successfully submitted is used by
app/code/core/Mage/Contacts/controllers/IndexController.php
The translate (.csv) file used by the module is:
app/locale/en_US/Mage_Contacts.csv
I'm trying to override it in: app/design/frontend/MyTheme/default/locale/en_US/translate.csv
But thus far have been unsuccessful... Do I really need to override the controller action using a custom module just to translate this message? Thanks.
