i found i minor ‘bug’ and couldnt find it in the tracker.
In the german de.php the translations of the fields
’CoreAdminHome_YouAreOptedOut’ the is a ‘.’ at the end. The english en.php does not have these periods.
The code adds an additional ‘.’ between sentences.
If calling piwik/index.php?module=CoreAdminHome&action=optOut&language=de this results in two periods between the sentences in the optout message.
