I can't convert whole website to PDF with "Creat PDF from web page" because website need login?
I find the method " How do I download entire websites and convert them into one PDF? " at here https://www.quora.com/How-can-I-convert-a-website-into-a-PDF-online
* From the Tools menu, click on “Create PDF”
* Select “Web Page”
* Enter your URL and select the “Capture Multiple Levels” checkbox Select “Get entire site”
* Click “Create”
But when I copy the steps, I find the errors in pages like the picture below, it seems need to login first. But I can make sure I have login in Chrome broswer and can browse the web pages build with grav CMS system ( a flat bolg system).

How can I resolve this problem?
