The images have stopped rotating on my site http://hipnosisybienestar.com
I use the rotor to rotate banner header images.
I updated drupal and all modules but still not working.
I have reviewed the settings, and everything is correct, drupal does not identify any error.
looking at the error console in firefox I found the following error:

Error: TypeError: $. Fn.cycle is undefined
Source File: http://hipnosisybienestar.com/sites/all/modules/rotor/rotor.js?k

could be the reason it does not work? Someone knows how to fix it?
Thanks
