If you are getting the error code: "Sorry, but this form could not be processed. Please contact site administrator." when you or your customer attempts to use your built-in website contact form for your Boutique Store Builder, there is a simple fix!
This error means that you're missing the admin email setting and the store builder doesn't know where to send these messages.
To resolve the error, simply input your preferred email address for contact form messages and all other store builder notifications into Store Admin > Site Settings > Admin Email. Be sure to save your changes.
