Apache2: module evasive20_module is already loaded, skipping

Question

I am installing mod_evasive on my Ubuntu LAMP server. I followed the simple directions:

sudo apt-get install libapache2-mod-evasive
sudo mkdir /var/log/mod_evasive
sudo chown www-data:www-data /var/log/mod_evasive/
sudo vi /etc/apache2/mods-available/mod-evasive.conf

<ifmodule mod_evasive20.c>
   DOSHashTableSize 3097
   DOSPageCount  2
   DOSSiteCount  50
   DOSPageInterval 1
   DOSSiteInterval  1
   DOSBlockingPeriod  10
   DOSLogDir   /var/log/mod_evasive
   DOSEmailNotify  [email protected]
</ifmodule>

sudo a2enmod mod-evasive
sudo /etc/init.d/apache2 restart

But whenever I restart Apache, I receive the following warning:

[Mon Jan 28 20:27:16 2013] [warn] module evasive20_module is already loaded, skipping
 ... waiting [Mon Jan 28 20:27:18 2013] [warn] module evasive20_module is already loaded, skipping

I tried running perl /usr/share/doc/libapache2-mod-evasive/examples/test.pl to test it out, however I keep receiving HTTP/1.0 200 OK, never a 403 Forbidden. Does anyone know what might be going on? As you saw above, the configration is located at /etc/apache2/mods-available/mod-evasive.conf and the load file (/etc/apache2/mods-available/mod-evasive.load) contains:

LoadModule evasive20_module /usr/lib/apache2/modules/mod_evasive20.so

I would appreciate any help. Thanks!

The module is trying to load twice, so you should comment out one of the following lines:

If you're using Apache 1.3, in /etc/httpd/mods-enabled/evasive20.load comment out

LoadModule evasive_module /usr/lib/apache2/modules/mod_evasive.so

If you're using Apache 2, in /etc/httpd/mods-enabled/mod-evasive.load comment out

LoadModule evasive20_module /usr/lib/apache2/modules/mod_evasive20.so
