Please download and copy the head.js script to your /sites/all/libraries/headjs folder

I also have the same problem :S

ah wait, should of read the readme. I advise you do the same :)

I've read the readme, im still getting that error, can you tell us how you fixed it?

In order to fix this issue, please download head.js from http://headjs.com/#download and copy the files into /sites/all/libraries/headjs

The final directory & file structure should look like this:

/sites/all/libraries/headjs/head.min.js

and

/sites/all/libraries/headjs/head.load.min.js

Well I had only copied a single head.js script into libraries/headjs/, after putting head.min.js and head.load.min.js in there as well, cleared the cache, did a refresh and everything was working as it should. If you are still getting errors after this check the permissions on the .js files, make sure your server is able to read them. I should also note I'm running the dev version of this plugin.

Hope this helps

I would also suggest maybe making it clearer on the module page which head.js files need to be downloaded and used... it seems like you only need the one at the moment
