I have been using weewx for over a year and it has been working well until yesterday. I inadvertently disconnected the USB cable to my Vantage Pro2 weather station and did not realize it until this morning. I reconnected and did a reboot on the processor (a Pi Zero) and the program worked as expected: updated all the records and also uploaded the missing data to Wunderground. However, when I log onto the Pi and use Chromium to look at
http://localhost/weewx/ the images are all stuck at the time when the USB connection was lost.
The image files are, in fact, being updated. I can force the browser to open the new index file by using the address - file:///var/www/html/weewx/index.html and all looks correct.
Thanks!
