What particular issue is this causing?

If I use `require 'site_setting_extension'` in my plugin, then I need to remember to add `require 'distributed_cache'` before.

The trouble is that now you are initializing site settings earlier than when the app does.

Can you post the exact code of what you are trying to achieve.

I use `SiteSettingExtension.module_eval` in my plugins to add custom site setting types, e.g.:

```plaintext
require 'distributed_cache'
require 'site_setting_extension'
SiteSettingExtension.module_eval do
	alias_method :core__types, :types
	def types
		result = @types
		if not result
			result = core__types
			result[:paypal_buttons] = result.length + 1;
		end
		return result
	end
end

```
