The wiki states that you need to have the php-gd extension installed and enabled. Please contact your hosting provider for further help.

thanks for the advise I can see the PDf Generated now but I am getting another error for sending the email if I use sendmail it gives an error ( Could not instantiate mail function ) and if I use SMTP it will be giving this error
SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting but I have downloaded the required files but I dont know where to put them and what function to activate so it will work ?

It didn’t solve this for me on PHP 7.2

$ php -m | grep gd
gd
$ php -m | grep mbstring
mbstring

The error persists.

…and was fixed by a combination of

# sudo  a2enmod proxy_fcgi setenvif
# sudo  a2enconf php7.2-fpm
# sudo /etc/init.d/apache2 restart
