The title on the VisitsSummary::index() -page is not properly translated. In /plugings/VisitsSummary/Controller.php the function index() contains the following:
$currentPeriod = Piwik_Common::getRequestVar('period'); $view->period = $currentPeriod;
and the translation string in the template (VisitsSummary_Evolution) is:
'VisitsSummary_Evolution' => 'Evolution on the last 30 %ss',
This does not work for other languages than English because: 1) The $period is not translated 2) This assumes that plural version of the time period can be conjugated by just adding a letter
The period should be translated, and this means that actually new translation items must be added for day, month and year for this context.
