I, like so many others, have the same no data issue. Or the no information showing on the page issue. At least the webcam is working. Nothing else is though. In order to rule out some things (like cache) I tried logging on from seven different computers using four different browsers on each computer. Prior to opening a new browser I would clear ALL caches and stop any malware or virus software. The same thing occurs in all these cases. Hence on 28 different log ons there was ZERO information received from WU.
Going over to WunderMap and locating my station (KMTBELGR45) and clicking on it the very limited information that is shown is correct. Once you click on the link(s) to look at the station, it gives you the blank page. My CWOP updates have been golden with no data loss or drops. So it is evident that the data is going out there.
Having been on Wunderground for almost 15 years, it is very, very sad to see what is happening. I would have thought that one of the largest computer companies in the world would have the capability to make something that has worked so well for years and years continue to work. Unfortunately it appears as if they have taken up the Microsoft motto; "If it isn't broken, upgrade it until it is!"
I also think that they have pretty much given up on the Trello page. You can tell since the last "section" was "SUBMIT BUG REPORTS June/July 2018".
So it appears as if the Wunderground that we once knew and loved and supported has decided that we no longer deserve their support. Sad, sad day.
