I'm unable to change/resize the logo from Magento admin after installing a custom theme. I was finally able to change the logo by putting the .jpg file in pub/media/logo/, but facing issues in resizing the logo(175px * 45p*). I changed/added logo dimensions in /app/design/frontend///layout/default.xml but even that is not working.

Also I'm not able to disable demo store notice from magento admin.
Any workaround for this?
