Piwik 1.5 jqPlot of bounce rate not working

Hi,

I have upgraded to Piwik 1.5 from 1.4 and everything seems to work well so far. The only issue I’ve found is that the jqPlot graph for visitors bounce rate does not show up; all the other graphs are working fine except that one. Anybody else has that problem? Where would I need to check to fix this?

Thanks,

Camille
