how i can fixed this?

file too large..
ask your host to increase memory

That error indicates that your php doesn't have enough memory allocated to complete the operation. You can either increase your memory_limit setting in php.ini to 32M or to temporarily up your limits edit your includes/config.php file and add this line right under the <?php line:

ini_set('memory_limit', 32 * 1024 * 1024);

If you still get the error, increase it to 64 or 128 (it must be a power of 2).
