It lets you preview what a LearnDash .pdf certificate will look like without having to leave the certificate editing interface by adding a metabox with a Certificate Preview button to the Edit Certificate page.
If your certificate doesn’t seem to be rendering correctly in the preview, here are a few things to check:
- Be sure save changes to your certificate before you click the preview button; unsaved changes will not be reflected in the preview.
- LearnDash shortcodes (such as quizinfo and courseinfo) will be replaced with static preview values.
- Non-LearnDash shortcodes may not render at all and are not supported.
