Fix Cannot Trust a PDF or Print SmartSource Coupons in Acrobat
Question details
The user is unable to print SmartSource coupons because the PDF appears blank, displays an error stating that printing is disabled, or gets blocked by a modal trust dialog that prevents changing document security settings.

- Product
- Adobe Acrobat / Reader
- Device & OS
- not provided
- Scenario
- Attempting to open and print online coupons from SmartSource using a PDF viewer.
- Observed behavior
- The PDF loads as a blank page or throws a printing disabled error, and the user cannot bypass or modify the security settings due to a blocking modal trust dialog.
Ensure that your web browser and PDF reader are updated to their latest versions, as outdated plugins frequently cause DRM-protected coupon formats to fail during loading.
Add SmartSource to Privileged Locations to Trust the PDF
Use this solution to manually bypass the modal trust dialog block by adding the coupon provider's host URL or folder to your trusted locations in the PDF reader.
Sometimes a security dialog closes before you can click 'Trust this document', preventing the print function from activating. Adding the domain to your privileged locations allows the coupon script to run securely.
Launch your PDF reader, click on the 'Edit' menu at the top, and select 'Preferences' from the dropdown list.
In the left-hand panel of the Preferences window, select 'Security (Enhanced)'.
Under the 'Privileged Locations' section, click 'Add Host' and enter the SmartSource URL, or click 'Add Folder' if the temporary coupon PDF is saved locally. Click 'OK' to save the settings.
Close the PDF reader and your browser, then reopen the coupon link to try printing again.
