Hi. i'm a newbie here.. how do i add a logo ?
Welcome to the community.
The full site and the mobile site have different themes by default.
You can either:
try to set your full site theme as the mobile theme, by adding (or editing) this line in config.php
$Configuration['Garden']['MobileTheme'] = 'nameoftheme';
(Where the theme name matches your full site theme name.)
However, your main theme may not be optimal for mobile use, so if you do this I'd suggest doing it in a testing environment, to see how it looks.
Alternatively, you can create your own mobile theme (this is a lot easier than it sounds.)
Copy the mobile folder in themes, and rename it to what you want.
Make changes in custom.css in the design folder, or in the default.master file in views.
Edit the about.php file so that the theme name exactly matches the folder name.
The mobile theme you have made should now be available for selection via the dashboard.
