I use:
- wkhtmltopdf 0.12.1 (with patched qt)
- wkhtmltoimage 0.12.1 (with patched qt)
- Ubuntu 16.04.4 LTS (up to date)
- Odoo 11.0-20180529 (Community Edition)
But when I try to print invoice into PDF I get unformatted raw data. Just like there would be no template. Any idea what could be wrong and how to approach debugging of this?
