Setting theme in config/main.php doesn't work

Hello guys,

I have created a theme with a home view in themes/myTheme/views/site/home.php to substitute the default one in protected/views/site/home.php. I have set in config/main.php the theme as a parameter of the main array as ‘theme’ => ‘myTheme’. Nevertheless, the app just keeps displaying the home page from protected/views/site/home.php. Do you have any idea of what I might be doing wrong?

Thanks in advance!
