Colorbox has broken my site. Help! I had downloaded the libraries module. I then watched another tutorial which told me to CREATE  a libraries directory in the sites/all folder. WHich I did, I then downloaded the colorbox plug in and pasted it in the empty libraries directory. I am now getting the following error:

Fatal error: Call to undefined function libraries_get_path() in /Applications/XAMPP/xamppfiles/htdocs/drupal/sites/all/modules/devel/devel.module on line 407

I deleted both libraries directories to start from scratch but the error is still there. How do I fix this?
libraries_get_path is defined in libraries.module

Make sure the Libraries API module ( e.g 7.x-2.0 ) is installed and enabled.
