Actually my bad on the changes I recommended for the “wp_eStore1.php” file. I forgot that this functionality has been slightly changed/moved.
Please do the changes I suggested for the “wp_eStore1.php” file in the “eStore_payment_submission.php” file. Search for the following function in that file:
function eStore_get_custom_field_value1()
also don’t forget to upload the modified version of the file to your server overwriting the existing one.
