Hello,

Here is the error I'm getting when I try to send an e-mail. But in my Ubuntu server I have installed "wkhtmltopdf". 

Report (PDF)

wkhtmltopdf failed with error code = 1. Message: The switch --header-spacing, is not support using unpatched qt, and will be ignored.The switch --header-html, is not support using unpatched qt, and will be ignored.The switch --footer-html, is not support using unpatched qt, and will be ignored.wkhtmltopdf: cannot connect to X server 

Can anyone help me...

Thank You.
