 * Hi there,
 * I just updated from 1.7.13 to 1.8.1 and Collapse-O-Matic no longer works, please
   see Chrome Console error below:
 * Uncaught ReferenceError: colomatslideEffect is not defined
    at toggleState (collapse.
   js:90) at HTMLSpanElement.<anonymous> (collapse.js:570) at HTMLBodyElement.dispatch(
   jquery.min.js:2) at HTMLBodyElement.v.handle (jquery.min.js:2)
 * Is there a fix or should I roll back to 1.7.13?
 * Many thanks
    Warren

 * Many thanks
