Just purchased the SendGrid Auto-Subscribe plugin, but I can't access the settings page for it. The "com_sendgrid" page is just blank.

Also, as soon as I add the mod_sendgrid module to any page, that page stops rendering as well. The module settings are available, though they don't include any way to configure the sendgrid account etc to use.
