Cannot update support or newsletter e-mail addresses (button turns red)

Hi @josephjwilk, this forum post may help you: Unable to change email settings

Note:

There are two mail systems:
1. Bulk-email (sending posts to all members) - Mailgun settings configured in the members section of the admin area
2. Transactional email (signup/signin/staff invite) - Email settings configured in your config file

P.S. Welcome to Ghost! :slightly_smiling_face:
