admin I tried "turning it off an on again" then but it did nothing. Interestingly, we've had the same happen today....but I think I've worked it out. 0.00 was the amount in the "auto-charge-price-below" field, but I put that in there as it was 5p at my last settings. That seems to have been the culprit, as I changed it to 0 (just 0) and saved, and a few minutes later the charging started......perhaps something weird going on with that input field?
