[Plugin: Contact Form 7] Break on error

Forgot to report my functions.php file:

<?php

if( !is_admin()){
   wp_deregister_script('jquery');
   wp_register_script('jquery', ("https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"), false, '1.4.2');
   wp_enqueue_script('jquery');
}

if( !is_admin()){
   wp_deregister_script('jqueryUi');
   wp_register_script('jqueryUi', ("https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.0/jquery-ui.min.js"), false, '1.8.0');
   wp_enqueue_script('jqueryUi');
}

?>
<?php if ( function_exists('register_sidebar') ) register_sidebar(); ?>

What happens if you remove the functions.php?

If i remove the functions.php the problem still remains.

I work with it offline using mamp on mac osx, don’t know if it is related.
All the permissions are 755 for the plugins folder and for my theme folder.

Perhaps i’ve to set something on MAMP?

I’m sorry for my low knowledge, i’m learning wordpress! ??

Double post.

MAMP is no problem. Try deactivating other plugins AND switching to the default theme to rule out problems possibly caused by them.

I’m having this as well. It’s on a shared hosting environment. I developed the template, from the ‘Default’ template… I don’t think I’ve messed anything up. The only other active plugin is Akismet. WordPress 2.9.2 and CF7’s latest.

Well, i’m sorry that i’ve not replied in these last days, i’ve found that using an almost empty theme with only the contact form code on the footer i’ve no errors.
Late tonight or tomorrow i will start to cut out, one by one, pieces of my “buggy” theme to find what is going in conflict with the contact form.
I suspect that can be something with the jquery libraries and plugins calls that i’ve both in the header and in the footer.
As i’ll find the problem source i will post it here!

I found a solution to this.
it should work.

//if (_wpcf7.cached) {
if ( typeof(_wpcf7) != “undefined” && typeof(_wpcf7.cached) != “undefined”) {

I had the project in hold for some days, was working on another one.
The last things that i did are some changes to my theme on the scripts side, so i’ve now the contact form that says “email successfully sent”…but emails never arrives to my email box.
I’ve checked carefully the email address on the CF7 backend settings over the “To” field and is a working email.
I’ve tried also to change from a google one to an hotmail one address but same story, i don’t receive emails.

At the moment i can’t say nothing about the solution found by wjm until today late tomorrow, when i will work on this project.
Also later i will try to explain my changes to the theme that solved the “undefined function” issue.

my solution only fixes the javascript error message, but despite this error message it will send the message successfully. so those line wont solve your issue

I’ve all working fine about scripts etc, firebug don’t report errors.
But the mail isn’t sent.
??

Here i am!
I’m working also to another website, this one is a wp ecommerce website developed using shopp plugin.
I’ve included in a page a contactform7 email form without captcha and all is working fine, no-errors and email arrives correctly.
As installed plugins i’ve only contactform7 and Shopp.

I will investigate later on the other website that is causing me problems on sending emails to see if is something related with captcha or other scripts/plugins.

I’ve forgot an important difference:

On the website that contactform7 is working i’ve placed the form in a page placing the shortcode:

[contact-form 1 "Modulo di contatto 1"]

On the website that contactform7 isn’t sending emails i’ve placed the form on the footer using the following code:

<?php echo do_shortcode( '[contact-form 1 "Modulo di contatto 1"]' ); ?>

Don’t ask me how but now is all working fine for both websites, in the one that gave me problems i’ve only changed the form tags names.

Don’t know if the thread can be set to resolved because i’ve not at the moment a valid explanation.

@wjm

Thanks for this quickfix. I was finding it really annoying with firebug notifying me of this javascript error constantly while developing a site.

Cheers WJM!
