Hey everyone,

im trying to theme my new OC 9.1.0 Installation.
On the Desktop-Side everything is working like a charm but when you try to access the cloud with your mobile device the logos aren't visible.
Is there something in the styles.css which i have to change?

Thank you for your kind help!

Best regards,

Maxe

Google Chrome seems to have a problem with the .svg files after convert from .png with Photoshop.
Changed the image in the styles.css in my themes folder from icon.svg to icon.png.
Now all Browsers are displaying the right icon.
