Fix warning when accessing a 404 page

#155

Why will this cause an issue on the 404 page? This seems to be a site specific issue. Not closing it because I think there is room for discussions for this

@lesterchan When you reach a 404 page, do the WP-PostRatings js and css load or not? In my case, they do load and that causes the problem. With this PR, the problem disappears.

Yeap they do load, I think it is your theme issue though, it works on my end with 404, https://lesterchan.net/wordpress/asdasdasdadsd

Do you not get any warnings in your php logs?

[lesterchan]

Nope, my variables in the JS got loaded correctly, so that is why I say it is a theme issue, you can view source and see. In the #155, the line you pointing to is the config and it is global, there is no way it doesn't load on 404 page.

My guess is some theme or plugin is trying to do optimization on 404 pages and that breaks the plugin.
