your recordset is named BlogRS
this code is using a different recordset name:
echo(date("d/m/Y",strtotime($row_NewsPanelRS['ContentDate'])));
it needs to be:
echo(date("d/m/Y",strtotime($row_BlogRS['ContentDate'])));
NOTE: Instead of pasting the page code into the message, please compress the php page to a zip archive and attach the zip file.
