I host a Piwik 3.0.4 instance with one website registered on it.
Stats are exclusively collected from webserver logs. And the monitored website is static with
a folder/index.html setup.

When I view the pages report in hierarchical view I can see the row evolution of a page:

But when I use the flat view, I can't see the row evolution anymore:

This incorrect behavior could come from DataTable_RowAction.prototype.trigger in plugins/CoreHome/javascripts/dataTable_rowactions.js:
In the hierarchical view, the label sent to this.performAction() is set to label = "blog > 2015 > 04 > 10 > show-the-certificate-chain-of-a-local-x509-file > @%2Findex" whereas in flat view it is set to label = "@blog%2F2015%2F04%2F10%2Fshow-the-certificate-chain-of-a-local-x509-file%2Findex".
