take a look at your .htaccess
`RewriteRule ^([a-zA-Z0-9]+)/?$ ?c=$1&a=index [L,NC,END,QSA]`
this line says that if you have url like `xxx.com/hello/` it will put `index` as an action name

So you ALWAYS will have an action name and will be index by default,
so, please, drop this line
and also drop ALL `defaultAction` from controllers - they are ridiculous

Actually there is only one case when we can have no action in GET parameters - if we call handle method manualy and pass to it options manually
So you can leave default action name - but please make it `index` according to .htaccess
Or you can replace it with `default` in .htaccess
