Hello.

I have the same problem. What are the correct addresses that need to be entered? For example, my website address is site.com. What should I enter in these fields?

Hi,

Please uninstall your current wkhtmltopdf package and install it again. You can use the below code
sudo wget

sudo dpkg -i wkhtmltox_0.12.5-1.bionic_amd64.deb
sudo apt install -f

And also check the report URL sPlease verify that all the URLs in the system parameter is same as your URL Settings -> Technical -> parameters -> system parameters

On searching URL you can see the below options. verify the URLs are same as your URL
