# 12-Mar-2026 — walk leaders unable to save walks due to blocked Brevo config [ref #179](https://github.com/nbarrett/ngx-ramblers/issues/179)

## [build 520](https://github.com/nbarrett/ngx-ramblers/actions/runs/23028895903) — [commit 61634df](https://github.com/nbarrett/ngx-ramblers/commit/61634dfd91426948e6a374fad4d827974fb1b309)

The backup security hardening placed ConfigKey.BREVO in adminOnlyConfigKeys,
causing non-admin users (walk leaders) to receive a 403 when loading the mail
config. The frontend silently fell back to defaults with walkNotificationConfigId
null, so the notification system correctly blocked the save — but for the wrong
reason: the config existed, it just wasn't being served to them.
