Ajax Stopped Functioning

Hello,

Just updated to latest version of Gravity forms (1.6.3) and the Ajax no longer responds when a required field is not filled out.

Please advise.

Okay, now I'm in panic mode. All forms across the site no longer work. Please advise ASAP. Else, please give me a way to revert to previous version of Gravity Forms.

Okay, franticaly trying to debug. Here's a page to one of the forms:

http://www.aur.edu/american-university-rome/2012/02/study-abroad-for-summer-2012/

This one should redirect to the following URL once it is sent:

http://www.my.aur.it/ics/Summer_Studyabroad/Default_Page.jnz?portlet=Apply_Online_2.0&screen=Display+Form&screenType=next

No redirect. HOWEVER, the email is sent (which is good because we don't lose the contact!).
No Ajax.

Please help.

Yes! Setting ajax="false" fixed the problem, though not ideal, because if a required field isn't filled out, the page refreshes to the top and not to the form at the bottom... so the visitor doesn't see there is an error unless they scroll down. (You can see following the link to the form above.)

What now?

Yes, checking for conflicts by switching themes and turning off all widgets might be an option if I had a sophisticated sandbox set up for the live site. The problem is I do not; hence all "tests" would be live and as this a university website with the Hybrid News Theme and 70 + widgets, I can't do that.

I'm sure I'm failing a "best practice," however, all things were working fine prior to version 1.6.3 release. As such, it seems the onus should be on the update--and not the website itself--to have the means to identify the conflict, and not the other way around.

This update was real kick in the teeth. I expect better from Gravity Forms.

I have reverted to version 1.6.2 until it is clear that the newer version is fully functional and reliable.

OMG! Finally I found people here with the same problem as me. Ajax stop working since the last plugin update. And no, there is nothing related to the theme we're using. It used to work until now.

I made a test form you can check it here: http://www.happines.net/test-form
(text in red is the error debugged by firebug)
Using Activity window on Safari to trace the submit action it shows the following error:
"http://happines.nethttp//happines.net/wp-content/themes/catalyst/js/jquery.js"
So I guess there is a sintax error in some script trying to call jquery.js in the wrong place.

I hope this looks clear for you to help us.

@sebasg, I went back to 1.6.2 to fix the problem.

@alex, I am grateful for your help! However, I've got this on a live site with multiple forms, so I've got to know the fix is confirmed before doing further updates. I am sorry for this as I know it isn't a help to you if you can't directly inspect the problem.

It does look like others are experiencing it as well... hopefully you'll get direct access to one of them to better understand.
