Fatal error - [Plugin Akismet] Error when activating plugin Akismet on WP 3.0

When activated, the page plugin gives error:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7680 bytes) in /home/improv/public_html/wp-includes/kses.php(550) : runtime-created function on line 1

Solution:-

First, try installing the Memory Bump plugin.

If that doesn't work, here are four more ways to increase PHP's memory allocation:

1. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 64M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

2. If you don't have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 64M

3. Try adding this line to your wp-config.php file:
Increasing memory allocated to PHP
define('WP_MEMORY_LIMIT', '64M');

4. Talk to your host.
