j3.4+CB+uddeim+gantry visible problems

Hi,
I need uddeim with cb for my webproject, but after installation of all, there is white on white "From/To/Date" shown in the uddeim mailbox. When I try to write an uddeim mail, there is also white on white for topic as also for message, you can't see what you write. Even the symbols above the smileys are extremly small.
I use the gantry 5 framework with hydrogen theme.
I went through all kind of css and scss files to find the right colors, but I didn't get it
Please help me!

Thanks!

It doesn't seem to be the failure in uddeim directly, I am not sure, but in Joomla (Template gantry perhaps) or in CB it might be, I suggest.
Because in the user profiles from CB there is also in the Article and Blogs section this problem with white text on white background.
But also in the mailbox.

Would be nice if anyone could guide me throught this horror
A workaround or solving.

Merci.

also the list view of users shows white usernames on white background.
seems totally to be the failure from CB?

Well, also Kuena. The Gantry Framework might not be compatible to all the components.
Makes me sad, because I liked this framework for doing my own design, instead of all the "free" light templates with backlinks and all the jokes.
