WeeWx: Import of driver failed. (interceptor)

[Joerg Strobel]

Hi, 

i have the following problem with WeeWx. I have to use the interceptor driver, because of sniffing.

At the first start after installation everyhing worked fine. So i think the weewx.conf is fine.My RPI got all the packages and the html file was fine.

After installing a new weewx skin and deleting all the files in the /var/www/html folders wait for the new files, but nothing came in. So i checked the log.

Does someone has an idea what to do?
