Issue: can't get first accordion item to collapse.
Background: previously, the only way I was able to get my accordions to collapse was by checking the 'Old Version' checkbox in WP UI Settings -> Advanced to implement the old UI API instead of the newer one. This worked okay, up until WordPress 3.5. Upon updating to 3.5, I had a jQuery conflict that was resolved only by unchecking the 'Old Version' box. jQuery fixed. Accordion no longer collapsible.
Any ideas on how to fix this? Thanks!
