(Translated from Italian)
The research I had done on this topic but there are so many threads and I could not understand what was the right one. However, the file was installed before Yahoo5Weather.r2skin, that I found, but the effect is that the image of my previous message. What I have suggested is a folder with other folders and a file. Even with that, I copied the folder admin/.rainlendar2/skin, the effect is the same, as you can see.
In the Options / Themes I do not think there are particular settings to do besides write your preferred location.
Thanks for your attention.
