I use Piwik in a closed environment and we don’t really need to collect users’ country and language. So I thought I disabled the UserCountry and UserLanguage plugins but I found out that disabling those plugins resulted in some MySQL query errors saying that default country and default language is not set.
we’d like to propose a good solution for this as for sure no error should happen when you disable some plugins. Maybe we could even add automated tests that test with many plugins disabled.
