Accordion (toggle) stopped working-but only on one page

Hi there,
Urgent matter, as we need to transfer DNS very soon.

On the first page below, the accordion will no longer open.

The copy is still in the accordion, however–we have not deleted anything.

Other toggle/accordions are fine, for example, the second one.

Your ideas on how to fix the first one? I deleted a few items from the accordion, thinking perhaps there’s a limit on how many should be there.
Thanks in advance.

Kathy
