In a fully functional piwik install with ssl support, all the pages produce warning in navigators (tested with chrome, but classical issue) due to protocol error when retrieving piwik logo :
The page at 'https://analytics.example.com/' was loaded over HTTPS, but displayed insecure content from 'http://analytics.example.com/plugins/Morpheus/images/logo.svg': this content should also be loaded over HTTPS.
It was OK with 1.12 version, since upgrade to 2.0.2 there is this issue.
Keywords: morpheus ssl
Thanks for the report!
