Hi,
Sorry for the delay because we have just on the four-day Holiday of the Liberation and International Labour day.
You can rename the theme by changing ‘sns_lunar’ at the directories: skin\frontend\default\sns_lunar, app\design\frontend\default\sns_lunar By YOUR_NAME.
After that, please go to the Configuration >> Design >> Themes, and set ‘YOUR_NAME’ at the Default. Refresh cache and reindex Data.
Thanks,
