Drupal JQuery broken?

Not sure what's going on but the Jquery.js is dying on me with "d is not null". This came out of no where. I can't seem to figure out how to fix it it.

Screenshot of firebug:

From this drupal link link Michelle (3rd comment) claims this is Collapsible forum containers issue? (Which as far as I know I am not using?) but it doesn't seem to help?

Anybody have any开发者_Python百科 suggestions?

Thanks!

I was having the same problem, but really needed the functionality of Webform Conditional. If you really want to use Webform Conditional, you might try making the fixes suggested on this page:

Worked PERFECTLY for me.

I disabled the Webform Conditional module and the problem disappeared.
