Hi,
Let's say I navigate to Hikashop > Hikaserials > Configuration (or any other view), if from here I click the "Dashboard" button of Hikaserial, I get this fatal error:

/administrator/components/com_hikaserial/classes/statistics.php:20
Compile Error: Declaration of hikaserialStatisticsClass::getDashboard($place = null) must be compatible with hikashopStatisticsClass::getDashboard($place = null, $all = false)

And please, don't forget about pushing this hotfix: www.hikashop.com/forum/hikasubscription/...cription.html#368609

Thank you!
