 * Hello,
 * When i try to download an invoice from the order page (or from orders list) i’ve
   a blank page or an Err_invalid_response fromme Chrome.
 * Status page from WCPDFInvoices is all green except opcache in orange.
 * is that because of the new version of WordPress 5.9.3 ?

 * I have a similar issue after wordpress 5.9.3 update.
    When i click “pdf invoice”,
   Chrome give me the following error: “Errore Impossibile caricare il documento
   PDF.” (“Error Impossible to load the pdf document”)
 * Edit: If I choose the html format, I got the invoice.

 * Same problem… “ERR_INVALID_RESPONSE” after updating the plugin itself a few minutes
   ago.
    Impossible to download any invoice or packing slip. Doesn’t work on both,
   neither Safari nor Chrome. Help!

 * I have solved (partially) the issue.
 * Solution #1
    Change the format from PDF to HTML
 * Solution #2
    Go to plugin settings -> Status -> Click on “Create a new temp folder”
   Go to plugin settings -> General -> Select “open the pdf in a new tab of browser”
   on “How would you view the pdf?”
 * If I use the 2nd solution I can print pdf files.
 * PS: I have translated from Italian to English the plugin settings text

 * Thanks for reporting this error, and I’m sorry for the inconvenience! It appears
   this was related to the `Content-Length` header we added in the last release,
   affecting the “Download” option for the “How do you want to view the PDF?” setting(
   General).
    We have now reverted that change and released a new version: 2.14.4
 * The download option should now work too, but please let us know if you continue
   to have issues!

 * Thanks
