Hi,

We just released a hot-fix which must solve the issue. It will be included with next update. To apply hot-fix now set please "E2Pdf" -> "Settings" -> "Release Candidate Builds" (Update from E2Pdf.com) (screenshot attached). Check for plugin updates, and update plugin to 1.11.03.1.

After applying update it's recommended to turn off this option.

P.S. If you will fail with updating plugin to 1.11.03.1, download please attached file "e2pdf-view.php.zip", unzip it and replace it via FTP at /wp-content/plugins/e2pdf/classes/helper/e2pdf-view.php

Let us know please all will start working like expected after update. Thank you.

We remain at your service.
