After upgrading piwik to 2.14 from 2.13.1 I now get this error:
“PHP function rrd_fetch does not exist. Please ensure you have installed PHP RRD functions: PHP: RRD - Manual”
Google, nor the manual article didn’t seem to help much. I am not quite sure where to start in troubleshooting this one.
I can view the administration pages just fine, but anything concerning the Dashboard just displays the above error.
