Your memory limit for your site needs to be increased. Here are a few methods to accomplish this, we recommend you start with step one and if it doesn't work continue to the next method (reverting what you did in the previous step):
1. Edit your wp-config.php file and enter something like:
Read more about this on wordpress.org, found on the wp-config wiki.
2. If you have access to your server's PHP configuration file, you can change the line in PHP.ini
If your line shows 16/32M try 64M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)
3. If you don’t have access to the PHP.ini file try adjusting your .htaccess file:
php_value memory_limit 64M
4. If those all fail to produce results you'll need to talk to your host.
