Hi Don,
I'm not sure about your # 1 ) problem, most likely it's linked to your # 2 problem.
# 2 is caused by an FTP error when connection to your webserver fails.
It can not upload your Cumulus data according your set interval time (5 mins or 10 mins).
Normally, it will re-try a few times automatically, although the error message is registered and shown on your Cumulus Screen.
I see the same happening every once in a while (error 426 'FTP Time out').
Just click on the red error light on your Main Cumulus screen and 'clear' the message.
If you DON'T want to have it displayed on your Cumulus Main screen, hence uploaded to your website, un-check the setting in: Cumulus/Configuration/Display - 'Show FTP errors on error log Window'
Hope this helps,
Cheers,
Arthur
