There is no data to export!

Where is the Problem ?

Source Code:
```
int ExportMonthDataToCSV(const Config *cfg, InverterData *inverters[])
{
char msg[80 + MAX_PATH];
if (cfg->CSV_Export == 1)
{
if (VERBOSE_NORMAL) puts("ExportMonthDataToCSV()");

if (inverters[0]->monthData[0].datetime <= 0) //invalid date?
puts("There is no data to export!"); //First day of the month?
else
{
FILE *csv;

ect.
........
```
