Error With Smarty

I have an error coming up in the header area of my member.php page.

Here is the error:
Warning: Smarty error: problem writing '/home/lovellte/public_html/reselling4profit/templates_c/541/541269446/0.php.' in /home/lovellte/public_html/reselling4profit/smarty/Smarty.class.php on line 546


Any suggestions as what to do?

thanks in advance,
Pat Lovell

amember/config.inc.php and set
