We used the default contact form and now the page has reverted to the "404 error page" I've tried to find the CMS page to edit this if it had become disabled, but it seems like it's not even listed in CMS pages. Thank you in advance. -John
The default URL of the contact-us might be "/contacts". The content is probably in CMS Blocks, not CMS pages. You can read more about it here: http://www.templatemonster.com/help/magento-how-to-edit-contact-us-page.html#gref
Have you checked if it is enabled at the first place? Try.. System > Configuration > Contacts >> set enable contact us field to 'Yes'.
FYI. There is no separate page for Contact Us in Magento. But to edit it.. "form.phtml" file can be located at " \magento\app\design\frontend\base\default\template\contacts" Thanks.
