Hi @paidtothink,
The PDF document itself is accessible by the link, this is one potential cause off the table.
Next, looking at the page in the browser’s Network tab, the PDF Embedder scripts are not being loaded on the page. If the scripts are not loaded, they are not able to generate the embedded viewer to display the document. This is often due to a conflict with another plugin or your theme.
We have a troubleshooting guide to help you find the conflict here: https://wp-pdf.com/kb/pdf-doesnt-appear-at-all-just-a-blank-line-or-hangs-on-loading/
If you have any other questions, please feel free to send an email to contact@wp-pdf.com as we may not see messages posted here to respond in a timely fashion.
