I have entered settings for in Cumulus according to postings I found here and other boards:
Weather Underground is checked - enabled
Rapid Fire is checked
interval is set to five minutes.
the station id is entered correctly.
and the password was entered correctly.
When I click on Debug then check the file after a few minutes I find that it isn't able to log into the site. the error is ID/Password is bad.
I went to their site and using my ID logged into there with the same password that Cumulus is supposed to use.
