Hello,
I have problem with migrating the custom reports module to v10, when i install Sales and print default report it looks fine, but as soon as i install my custom reports module(which is fro test purposees minimal), the header is lost on default reports as well as on my custom reports. Have someone encountered this? The version of odoo v10 is irrelevant since i tried on cultiple versions and got same result.
Thanks
If that happens when you install your module. You should check your template. You can post here, and we can help you.
