showhide doing odd things in latest wp update

Just update my wp version and now show/hide is doing odd things . . . it works fine early in the post, but as I add additional links the last ones don’t work – you can’t open them. And some of the earlier ones quit working if they have been opened and closed – you can’t open them again. It’s as if it isn’t seeing the link . . . I’ve loved this plugin, so hope it can keep working.

The page I need help with: [log in to see the link]
