After updating to version 6.3.0, I am having problems with the colors. No colors are being applied anymore. Everything is white! This applies to both the background and the text. Even when I select an image as the background, everything stays white. Custom CSS doesn't help either.

In the chat, I was recommended to downgrade to version 6.2.3. The team is working on this problem and it is known. Unfortunately, it also doesn't work with that version.
