There is no setting to disable preview verification within the system as the code is embedded within each screenshot request.  In order to remove it you must do one of the following:

If you are using the "Simple Method"

1. Remove the following PVP code from the header of your page(s):

<script type="text/javascript" src="https://shrinktheweb.com/scripts/pagepix.js"></script>

2. Remove the PVP code from your screenshot requests by using the Code Wizard in the STW Dashboard to generate new requests for your site.

If you are using a script

Check the version you are using, we have made all the necessary changes to remove the Preview Verification Page feature from all our supported plugins but there are certain cases in which the 3rd party software have not updated their software to accommodate the change.

 
If you are using a script that still has the Preview Verification Page as a required feature, please contact the developer and request that they update their software.
