Cumulus Support

Interesting behaviour on these graphs but not constant issue. Say if click for example on the historic graph and select air quality and select one of the graphs to view you will ever so often get a blank graph https://www.sheffieldweather.net/weathe ... graphs.htm or https://www.sheffieldweather.net/weathe ... graphs.htm.

Mx diags shows nothing amiss any ideas.

I can't see a problem, I clicked around like mad on both those pages and not a single hiccup?

One possibility, you just happen to request graph data when it is being uploaded to your web site. Do you use the FTP rename option to minimise the time the files are unavailable?
