I guess in 1902 it does not work if css files are put inside tenant-custom-res/000000000000001.
Put it in tenant-custom-res/ folder and test.
thanks for your answer, thats correct.
But my problem is in 18.11 - these are two different system. In 19.02 its working.
Just in 18.11 the changes of the css file were not updated. I will try like you said.
Possibly try clearing user's browser cache? Over here we forget to do that at times and we panic thinking the new changes aren't working. That usually clears the problem.
Do let us know how you fixed it.
also thanks for your answer.
I will try this on monday next week - I'm on training the next two days.
But I think, this is not the problem, cause several users on different pc's have this problem.
I will try this and give you response.
Best regards and thanks for helping!
