PROBLEM SOLVED!

I report my solution, willing to help anyone still having this issue.

1) Go in your /var/log/odoo/odoo_log_file and check the last lines
2) You'll probably find out a missing function in your payment.py file.
3) sudo nano /opt/odoo/odoo/addons/website_sale/models/payment.py
4) find the missing function: it is somewhere called, but never defined.
5) comment it
6) problem solved

just found solution - in my case installation of wkhtmltopdf solved problem:

  wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-jessie-amd64.deb

  dpkg -i wkhtmltox-0.12.2.1_linux-jessie-amd64.deb

  cp /usr/local/bin/wkhtmltopdf /usr/bin/

Hello,

Just to confirm - this problem seems to be 'standard' one, I am facing it as well; in my case it is fresh odoo 9 installatin, I've so far:

- created product (sale module)

- created event (events) connected to product created in step above

- tried to sell ticket to the event

Problem is visible in all possible cases: anonymous web access/client access, acces with admin account and access with regular user account. If anyoune would find out where probem is and could share - I would appreciate. Related entry from odoo-server.log is below, I will try to understand it, but maybe someone is more familiar with python?..
