Cumulus Support

I'm finding that Select-a-graph gives me a blank grid when I try to view recent data. If I try to show today's temperatures, for example (22/12/13 00:00hrs to present time) the chart just shows 0 in the centre of the Y axis and 00:00 at the centre of the X axis. No data curve. If I move the start date to 22 November I get a similarly blank graph but with the tick mark at the centre of the X axis now showing 30/12/1899! If I move the start date into October then I get data showing up to the end of October, but not beyond.

I'm assuming I have some data corruption, but I'm not sure where. I've eyeballed November's data but can't see anything obvious. Logging changed from 1-minute intervals to 5-mins on the 14th (at around 3:30am, so unlikely to be anything I did) and then back to 1-minute later in the months, but that's about it.

It looks like I might have updated to a new build of Cumulus in early November (I have a downloaded version of 1.9.4 setup date stamped 4th Nov) but don't know whether that's relevant. I've tried updating to build 1086, but no change.

Does anyone recognise these symptoms, or have any suggestions on what to look for in the data files?

Perhaps you have edited your datafile and the date changed from DD/MM/YY to DD/MM/YYYY (year with 4 digits instead of 2) ?

Bingo! I have no idea how I failed to spot that - it's glaringly obvious now. Thanks very much.
