Uncaught ReferenceError: gf_apply_rules is not defined

Hello,

I have looked at a similar post. But can't seem to seem to find an answer.

I can't understand what has changed in my theme - to cause the problem, as it was working fine before.

I am getting a javascript error 247Uncaught ReferenceError: gf_apply_rules is not defined on my sign up form which is using conditional logic.

It seems to be conditional logic which is causing the issue I think.

I have 3 forms running on the website...
http://suzukibulletin.co.uk/contact/
http://suzukibulletin.co.uk/2012/04/26/suzuki-bulletin-launched/

and the broken one...
http://suzukibulletin.co.uk/sign-up/

It completely kills all the javascript running on my page - and I don't understand as it was once upon a time fully working! I've disable all the plugins and it's not a plugin conflict. I've removed every single script from my theme template files, and still not working. The last entry was yesterday, and the only thing I changed today was by adding the 'Google Sitemap Generator' plugin, which I've disabled now.

I'm loading my jquery at a higher scope in head than the wp_head and the wp_footer is definitely in place.

I don't suppose you have any other ideas into why this could be happening?

I am using the latest WordPress 3.3.1 and gravity forms 1.5. If your finding it strange too I can provide you a login.

Many Thanks
Josh

Hi Rob,

Thank you for such and immediate response. Of course I can see why now.

I was adding this into my functions to stop another jquery file being loaded in the wp_head

// JQUERY DEREGISTER
if( !is_admin()){
	wp_deregister_script('jquery');
}

But perhaps this was removing all the jquery scripts from the head. I was trying to only remove the jquery library itself, not all jquery scripts. Durrr!

But why does a gravity form conflict with my other jquery elements on the page. If you look in the side bar on any form page , it messes up my sliders. http://i.imgur.com/krmlX.png

It's very strange. I am using http://bxslider.com/ for all my sliders. It is just a plugin conflict?

Thanks
Josh

Hmmm yeah I can see that error too.

Thanks for your help Rob.
