Thanks for the quick response and the fix. It works now as expected.
Yes, I tried it first with default US format.
I think it something with the syntax.
It is documented as:
Valid [postexpirator] attributes:
type - defaults to full - valid options are full,date,time
dateformat - format set here will override the value set on the settings page
timeformat - format set here will override the value set on the settings page
So what is correct way to specify these?
[postexpirator type=full 15-08-2018 10:00]
or
[postexpirator full 15-08-2018 10:00]
or something different?
