Hi @sjo007,
Sorry about the issues with latest update. The developers are investigating the issue. If you have a back up copy, you can rollback to that version. If you don’t have a backup copy, please go ahead and update your plugin to version 5.0.1.
The 5.0.1 version is the exact same copy as the previously working Premium 4.4.3 / Secure 4.4.5. We reuploaded the older, working version and only updated the version number to make it easier to do the update, but the code is identical to what you were previously using prior to the 5.0.0 update.
Important: once you update the plugin, please flush any caches on your site and the browser, then reload the page where you have the embedded PDF.
If you are a Premium or Secure user and are still encountering an issue after updating to 5.0.1 AND flushing your site and browser caches, please let us know by sending us an email to contact@wp-pdf.com.
