How do you delete a cert?

[lilsense]

I have installed a cert and now want to remove it from the Trust-> Certificates, but the trash icon is not next to it. How do I revoke and remove it.

You can only remove it if it is not in use. So first remove it from all configuration sections that reference it.
Web UI and OpenVPN are likely candidates.

Thanks. Fixed. :)
