I have looked through and tried all the suggestions from here and github. I have checked my wkhtmltopdf version (0.12.1 patched with qt), I have tried changing the web.base.url parameter, adding the freeze parameter, etc. My headers are still missing from PDF reports. The system seems to be able to do the rest, as Bootstrap elements appear, as does the footer. I did see this message show up once:
2015-01-20 17:16:21,146 22730 INFO JB-1-19 werkzeug: 127.0.0.1 - - [20/Jan/2015 17:16:21] "GET /web/binary/image?model=res.partner&field=image_small&id=3&resize= HTTP/1.1" 304 -
Any more things to try? Would be nice if a fix for this was included in Odoo . . .
open your report from setting=>technical=>actions=>reports in your report click on Other Information tab you need to check "Add RML Header" then the header will appear in PDF report
Anyone have an answer for Odoo 8?
