Hi guys.

I have looked around for this problem, and i cannot get my head around what is going on?

Im recieving this message from my sitehttp://www.astrongerlife.dk

Declaration of Concrete\Package\HwBackToTop\Block\BackToTop\Controller::registerViewAssets() should be compatible with Concrete\Core\Block\BlockController::registerViewAssets($outputContent = '')

I know that google have changed their rules about API etc but i just want to get rid of the error so i can include openstreetmaps instead.

Thank you so much for your time
