I'm unable to get this plugin working (v 1.3) with my site. I've tried both CSS and JS and both and each one seems to throw these 400 and 500 errors.

I'm not sure what's going on, as the URL's don't seem right. Some of them include things like /../path/to/file instead of the actual path.

I also tried to activate pretty URL's but I'm getting an error that an .htaccess file doesn't exist which it does. And then it tells me to place some code in the file, which I did but it doesn't seem to help. I'm still unable to save the pretty URL setting.

I've had to deactivate in the meantime until this is resolved, as the front end of the site is all mashed up and pretty unusable.
