 * [@javierpernettr](https://wordpress.org/support/users/javierpernettr/) You mention
   that “all in one wordpress security” Plugin blocking the functionality of pdf
   poster. Have you got any possible solution ?

 * Sorry, it’s not the AIO-Plugin. You need to change the code in the pdf-poster.
   php from the following line
    ———— $viewer_base_url= plugins_url().”/pdf-poster/
   pdfjs/web/viewer.php”; $final_url = $viewer_base_url.”?file=”.$file_name.”&download
   =”.$pdf_download.”&print=”.$print.”&openfile=”.$openfile; ————
 * to this code:
 *  $viewer_base_url= plugins_url().”/pdf-poster/pdfjs/web/viewer.php”; $final_url
   = $viewer_base_url.”?file=”.urlencode($file_name).”&download=”.$pdf_download.”&
   print=”.$print.”&openfile=”.$openfile;
 * Then everything works OK.
 * This bug in the plugin-code was already fixed here by [@joneiseman](https://wordpress.org/support/users/joneiseman/):
