Try this...(using an earlier suggestion to the thread)

SELECT
  SUM(acctinputoctets + acctoutputoctets) AS Total
FROM radacct
WHERE
   radacct.username='%{User-Name}'
   AND acctstarttime BETWEEN CURDATE() AND NOW()
   AND (
     acctstoptime  <= NOW()
     OR acctstoptime IS NULL
   )

But in reality, can you have an acctstarttime that is >= NOW()? If not, 
then you can also simplify that term to just

   AND AND acctstarttime >= CURDATE()

and lose the BETWEEN comparison.
