Joomla 3.5.1
K2 2.7
PHP 7.04

What I'm getting is Item Creation dates that look like this: %PM, %05 %127 %2016 %19:%May

I tried just swapping over to a default joomla template in case my subclassing was the problem and that made no difference. Does anyone have any clue?

Problem turned out to be with the minik2 module 1.2.3

Thank you for sharing the solution Jeffrey.
