I get after selecting Import:

ImpEx Database errormysql error: Link-ID == false, connect failed
mysql error:
mysql error number: 0

it seems it is unable to connect to Tagret DB - but the instructions say that I can leave the TARGET info (@ImpExConfig.php) as default if I start within admincp.

The data from the source seems be ok.

Is this error message for Source or Tagret Database ?
