Hi, after activating W3 Total Cache my downloads stopped working. I can download them, but only with zero size. I use WP-DownloadManager plugin and I found following headers:
header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header("Content-Disposition: attachment; filename=".basename($file_name).";"); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".filesize($file_path.$file_name)); @readfile($file_path.$file_name);
It looks like Content-Length is somehow damaged by W3 Total Cache.
When I disable all cache types, everything works well (no need to deactivate the whole cache plugin). But when I activate any of cache (Browser or Page or something else), problem with zero size is back.
Thank you for your help.
