Customize Single Post page

OR how i get rid of contact details?

Kindly refer https://pluginsware.com/documentation/customizing-acadp-templates/ to customize our templates. For the single listing page, you should override the file under /public/partials/listing/acadp-public-listing-display.php

To simply get rid of the contact details, go to Classifieds & Directory => Settings from your WordPress Admin Panel, find the “Enable locations”, “Enable map” and “Contact form” options and disable them.

Hope, this helped you!
