Hello
I just updated from 2025.12 to 2026.9
The interface went completely white, replacing the blue bar and the light gray background.
Before I revert back to 2025, is there any way to restore the classic look & feel?
Thank you
Stefano
You are likely using a custom theme. Go to your profile and choose the built in light or dark theme.
If that doesn’t have colors that you like, use HACS to download one that fits your style.
