The full Framework Upgrade Patch changes all vertex sites to use jQuery instead of mootools and fixes various other issues..
For older sites:
If the Image and Content Fader has stopped working after a WordPress update, you probably updated the plugin at the same time.
If you use a theme older than Corporate Response or don't want to patch a newer one that is pre-responsive, you will need to downgrade back to the previous (mootools) version
of the plugin and remember not to upgrade again without the Vertex Upgrade Patch
