Hi @simbalion,
The “w is not a function” is due to a JS error from another source that is causing a cascading failure and conflicting with the PDF Embedder plugin. If you disable the PDF Embedder plugin, you will still see this error appear in the browser’s Developer Tools » Console tab. The error reported there should point in the direction of the script (located in the theme or another plugin) that is the source of this error.
If you have any other questions or require additional assistance in debugging this issue, please feel free to send an email with a link to the page or post in question to [email protected] as we may not see messages posted here to respond in a timely fashion.
