LogoBrowser Info Environment
I have just released a new version of the theme. After updating, you should be able to create a new stack named Site Name (or edit it if it already exists). If you add an image to the stack, that should be used instead of the default site name text.
hope this helps!
try the following: go to Dashboard -> Stacks. See if you already have a stack called "Site Name" or create one with that exact name. Then edit the stack and add any text or image you want to use.
