I recently upgraded to piwik 1.11.1 and now the visitor map and real time map does not display.
Piwik is installed on a windows VM using IIS. I installed it using the Microsoft Web Platform Installer. I updated piwik automatically.
I cleared the tmp directory, but that did not help. Also, I downloaded the zip of the latest version and overwrote the piwik directory.
Does anyone have any suggestions?
