Hi both, first of all chek this: if you go to: skin/frontend/default you shoud have a folder: hellopod_blue
Then go to: System, Configuration, under “Current Configuration Scope” select the theme (in this case hellopod), go to Design, and in “Skin (Images / CSS)” write: hellopod_blue, remember to Save the config.
I did this same very simple steps and it worked just fine. As Aaron said to you before, if you go to: System > Design and you have a design in place there, remove the design change.
Is not more than that. Tell us if you coud do it.-
