I tried again several times, without success.
I am using either Chrome or Firefox. I click on +Stations, fill in all required fields (lat,long,ht,Windht,Tempht; I accept terms, then press Save. Screen goes blank, then immediately returns to +Station, but no indication that registration was successful - no station ID, etc.
I really want to register and contribute to windy.com.

Do you have any further suggestions about how I might be able to register my station?

OK I tried that, but I still get back to the start: 'You don't have any station yet. '

I have a Davis Vantage Pro 2. I have tried to register using both Firefox and Chrome, with the same result. When I
click on Save, I am returned to the prompt that starts: 'You don't have any station yet. '
I succeeded in registering about a week ago, but accidentally deleted my station. I had ID f0749c9d. I have been unable to re-register.

I successfully registered my station, but then had problems at my end, so I deleted my station. Then I tried again to register, but when I enter details and press SAVE, I am returned to the registration page, but I don't get a station ID.
