Thanks in advance. Hello David.
I would suggest to look at our source code and to compare it. This has to work, it is tested by many users, as you can see from the comments, but we can check it.
Thank you for a fast reply. I choose to save the generated PDF on disk and it actually works. However, the project console contains the before mentioned error. I am currently testing different PDF generation options and have not tested it in live environment. This is actually my concern.
The solution that you posted is pretty simple and straightforward and I think I implemented it ok. But those should be the only 2 differences. Hi David.

I have an issue tho: Hello Mika. Maybe that will work. Do you know how it works under the blackbox of dinkto? My most basic css commands like background-color are executed, so I know the file is read, but apparently it has issue generating the template as it should. I am sorry, but I am not familiar with that at all. Never gone that deep into the dll. But I can only tell, related to CSS complexity, that css flex is not complex at all, in other words it is pretty easy to use, so you can try it for sure.
