Actually the full apache log is like that:
[Wed Aug 06 18:22:43.795185 2014] [core:alert] [pid 1827] [client 94.123.83.130:54441] /var/www/wp-content/plugins/akismet/.htaccess: order not allowed here, referer: http://www.sinematopya.com/2013/11/la-vie-dadele-2013-mavi-en-sicak-renktir.html
I'm using Ubuntu 14.04, apache, mysql, running wordpress with akismet plugin.
So is it a problem? If it so, how can I fix?
Could you post more information about your Apache configuration? Most likely, is is due to an AllowOverride None somewhere in your configuration. Try adding this:
<Directory "/var/www/wp-content/plugins/akismet/">
AllowOverride All
</Directory>
That's probably too permissive. You'll want to limit it somewhat, but if this works then you know the root issue.
I ran into the same issue and fixed this by adding the following to my Apache conf:
<Directory /var/www/wp-content/plugins/akismet>
AllowOverride Limit
</Directory>
then reloaded Apache using "service apache2 reload"
