Can you reliably replicate it? (If so, please outline steps):
Open Login with different browser
The issue you are facing:
I changed logo and background color with theming app. this is just working fine, but when opening login page with IE 11 or chrome (newest), the logo is just fine.
browsing with Firefox (newest) or Safari (testet on mobile) the logo is not shown.
any Ideas?
