Crash deleting monthly records

When WD did its daily crash and restart via WatchDog early this morning, monthly data disappeared apart from yesterday. So the monthly NOAA report, monthly climate report, and the monthly averages/extreme page lost all their data except for 29 March. This was happening regularly last summer but hasn’t occurred for many months. (The daily crash has continued to happen nightly but not the loss of data.) Is there a way to restore that data?
