I tried to edit the title of my store front. there was a confirmation that it has been saved and it would be updated in 2 hours. it has been nearly 2 days and it has not yet updated the title of the store front. i have tried multiple times to re save it, but i think there is somethign wrong because when i first clicked on update preview it used to work, but now it does not show any preview of what it will look like. although it does say it has saved the changes. how can i correct this. i am a basic free user, and have just started using this service.
