More likely, there can be an issue with difference hosts for your Opigno instance and pdf file. Check on _/admin/config/media/file-system_ that your settings are similar as on [the screenshot](https://drive.google.com/open?id=1aIu52pwpp-ocWQUS8nYF3_i0DD01V0Ja) When you upload the pdf file it should have the url like _public://2019-03/some.pdf_. Also, You can debug this using advice at https://stackoverflow.com/questions/37378251/load-pdf-on-foreign-url-with-pdf-js Olivier R.In reply to Opigno V2.1 by nikolayThu, 02/07/2019 - 10:05Thanks Nikolay for your help.Thanks Nikolay for your help.
