Hi Yenthe,

thanks for your good summary of what should be done!

With your help I got it to work! I'll explain my solution for others:

First I removed my other wkhtmltox with 'apt-get remove --purge wkhtmltox'

Then 'cd ~/tmp' and got me the 0.12.1 wkthmltopdf with 'wget http://download.gna.org/wkhtmltopdf/0.12/0.12.1/wkhtmltox-0.12.1_linux-trusty-amd64.deb'

I installed it with 'dpkg -i  wkhtmltox-0.12.1_linux-trusty-amd64.deb' and then copied the files to /usr/bin/ with

'cd /usr/locale/bin/'

'mv wkhtmltoimage /usr/bin'

'mv wkhtmltopdf /usr/bin'

I verified the version with 'cd -' and 'wkhtmltopdf --version'

Then I restarted odoo and went as Yenthe explained to  Settings > Technical > Parameters > System parameters and changed the web.base.url parameter to http://mywebsitewithodoo.com:8069

I figured that I did not need to set web.base.url.freeze to True

Thanks a lot!
