Since the skin is just an output of the database you can delete the contents of your html folder and weewx will copy them back on it's next archive interval.
I'd take a backup of the folder (just in case), delete the html folder contents, restart weewx and wait for it to repopulate the files. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
