How to stop blocking pdf from displaying?

  • Posted December 10, 2014

I am new to web development so I do not know what exactly causes the problem: apache2 or ubuntu or something else. Yesterday I followed this tutorial ([ and deployed my fist app online(Ubuntu 14.04 and apache2). It is written in Flask/Python. My app writes some data to a text file which is used later for generation of a pdf file which is displayed to the user using PDF.js extension. Unfortunately, a pdf is not displayed because either a text file was not generated or pdf is blocked from displaying. Everything works great on my local server. So, I am wondering how to give permission for writing a file and displaying a pdf. Any suggestions are highly appreciated!



Hi there, I’m having the same exact problem. I’m getting a 404 error. Was this problem solved? Thanks!

Yes, I get this error in the browser “Not Found. The requested URL was not found on the server”.

What does occur when you try to view the pdf? Are you receiving any error messages either in the browser or in your Apache log files?
