**Cure this (if you have a weather station type that has a log that Cumulus reads) by looking in "''Cumulus\backup''" folder, and finding a backup directly in that folder or in "daily" sub-folder for just before the problem. With Cumulus stopped, copy all the files in that backup into the "'''Cumulus\data'''" folder, and then restart Cumulus.

If you are viewing or editing log files at the time when rollover takes place, it is likely that some parts of the daily rollover will fail.  Although Cumulus 1 provides the functionality to view and (except for the data file) update the log files, make sure you have exited out of the built-in viewer or editor before rollover is due. If you inadvertently forget this, the cure of overwriting files mentioned above is applicable if your weather station has an internal log and it is around 2 logging intervals (see [[#Cumulus_takes_a_long_time_to_download_the_data_from_my_Davis_station_at_start_up]]) after rollover. When using an external editor, close Cumulus 1 or Cumulus MX before opening any Cumulus file.
