• There’s an error in the plugin code that causes it to fail with AIOWPS when you enable the additional firewall rules. On line 153 of pdf-poster.php it should urlencode the file_name. Here’s what the line should look like:

    $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;
