After I added a 2nd Webhook (for testing purposes), the Webhooks page (https://www.patreon.com/portal/registration/register-webhooks) is completely blank and nothing loads anymore.
If it helps, I get this javascript error on the page: https://content.screencast.com/users/SharedDocs/folders/Jing/media/8fe33787-5bd7-4cc1-9904-ec2e39f8b71e/2018-01-23_1310.png
