After updating my DokuWiki, statistics plugin and CentOS the dashboard doesn't pull any data and thus only gives me zeros or no graph (it seems to draw the x- and y- axis but that's it...).
The backend seems to be fine since it still logs everything nicely within the MariaDB. That should also rule out connectivity issues between the plugin and the DB.
I suspect that PHP is the culprit since the apache error log is full of those error messages:

I am not a prgrammer but to me the error either looks like there is an error in the script or the new PHP-Version fails to handle the script properly (The vulcan way of stating the obvious... :D ).
My wiki runs on CentOS 7.2.1511 Core and as a DB I am using MariaDBs latest iteration for the statistics. My PHP-Version is 5.4.16. I have also disabled all non-essential/3rd-party plugins.
How do I get rid of this? I do have a snapshot of the VM just before the updates but I have invested a bit of time tinkering with the machine since (also other plugins). I am also eger to learn why the dashboard falls on its face instead of finding a way to "ignore" the problem.
