COM_CMC_SUBSCRIBE_FAILED 400: The resource submitted could not be validated. For field-specific details, see the 'errors' array.
I receive the error when editing a profile both front end and back end. In the plugin the list is selected, the required fields are selected under fields. When editing, I check the box and enter an email address.
I have tried leaving fields blank and using the field mapping for email (the only required field), and receive the same error.
I have added the module selecting the list and attempting to select the field and use a field mapping. Under fields in the module, email shows as COM_CMC_EMAIL*. If this is selected I can get the module to allow me to subscribe and unsubscribe. I cannot get the first or last name fields to map when using the email in fields.
With the module on the page and the plugin enabled. When I am subscribed, it shows on the plugin when editing. I am unable to unsubscribe from the plugin.
I am not sure if this is a compatibility problem with other plugins, but I have disabled everything one at a time to troubleshoot with no change in the results.
