This was reported in several forum threads for example this message
The problem occurs while downloading Scheduled reports, while using custom date range.
For example on demo at: report request I get:
Fatal error: Call to undefined method Piwik_DataTable_Array::getRows() in core/ReportRenderer/Pdf.php on line 333
Let's add a test to replicate this bug when fixing it.
When "Sending email report" is clicked I see the HTTP request replying with a notice:
