@Mike Singer - I think IBM/TWC has begun to block all non-data account calls on their data URLs. After installing WWL 7.2.73 on Aug 9th none of the TWC maps worked. I also had some of TWCs new map URLs bookmarked in my browser and they now come up as a blank page also, although prior to around midnight on Aug 8th, my updated bookmarked map URLs worked. If IBM/TWC is not blocking unpaid calls on their URLs Mike, then maybe you can figure whats going on here. I always thought that free access to their maps was a backdoor that somebody would lock sooner or later.
If you put this prefix http://i.imwx.com[/url] on the TWC map URLs and remove this one [url=http://fcgi.weather.com]http://fcgi.weather.com Then all of the TWC map URLs from WWLs Map Manager will work.
The “http://images.weather.com” prefix also works. TWC is most likely having technical issues or they are doing some cleanup on their end.
Mike, I had the “http://images.weather.com” prefix fail profusely on all of the TWC map URLs that I had bookedmarked, on Tuesday evening Aug 9th.
Are you using Weather Watcher 7.2.74? If not, please try upgrading.
