Fixed Fatal error

When I try to activate the plugin, I get a fatal error saying that wordpress cannot call undefined function add_options_page().

The solution is to change line 34 in file wp-content/plugins/effective-spambot-stopping/effective-spambot-stopping.php to:
add_action('admin_init', 'fsml_add_options_page');

You must use the hook admin_init instead of admin_menu.

But when I try to configure the settings, I get a permission error:

You do not have sufficient permissions to access this page.
