PHP code in theme and date in post

Hi

Its not possible to set the date in post, you need to set all the things in the campaign, like date(when to expire the countdown) and just put the shortcode of the campaign in your WP pages or Post.
If you need any other help then please submit a ticket here: https://www.pageexpirationrobot.com/v2/plugin-support/ and we will get back to you.

Thanks
