Deprecation notices

I’m on 3.0 but still get these message appearing :thinking:

Along with another one:

Deprecation notice: SiteSetting.secure_media has been deprecated. Please use SiteSetting.secure_uploads instead. (removal in Discourse 3.0) At /var/www/discourse/lib/site_setting_extension.rb:211

Any suggestions on how to work out which plugin is causing these warnings?

Before this happens :scream:
