I get the following error when trying to create/save a new item

DateTime::__construct() [datetime.--construct]: Failed to parse time string (K2_J16_MonPMMSTE_November-0700RNovPMMST_CPM0E1MonPMR) at position 1 (2): Unexpected character

Not sure how to fix. New to this component. Here is link to the site.

Please reinstall K2. I cannot see any of it's language strings.

Thanks that seemed to have worked!
