After update to piwik 3.0.0 there is a little bug in the visitors overview.
If i use English language:
Visits Overview
66,317 visits, 11,426 unique visitors
If i us German Language:
66.317 Besuche, 11 Eindeutige Besuche
Same problem still exists in the Dutch translation. 7557 visitors is displayed as 7,56 visitors while the English version shows 7,557 (earlier it showed 7,5 for 7502 visitors)
