jQuery Conflicts WordPress


So I have customized a theme and added a few plugins and the Nivo slider does not seem to be working right, - it does not arrow advance or add amimation to the slides. I switches the images, in a slow, strange way - but that is it. When I disable the WP NextGEN Gallery and or the Quotes collection ( - the slider works fine, but the plugins do not obviously.

I know you should use wp_enqueue_script('jquery'); - which the quotes plugin uses, but so does the theme, I need the answer on how to get this to work right and for the future as well - I have run into jQuery libraries conflicting and screwing things up.

I can give you access to the admin, just need this fixed!

I guess the url would help -

I notice that the jquery library is being included twice on your site. If you view the source you'll see what I mean.

<script type="text/javascript" src=""></script>

<script type='text/javascript' src=''></script>

I believe the second one is coming from the NextGEN Gallery plugin. If I recall correctly, in the settings for NextGEN in the WP admin there is an option for "don't include the jquery library". Try activating that option to see if it makes a difference...

I also see this error which may be causing a problem:

Error: invalid assignment left-hand side
Source File:
Line: 147, Column: 30
Source Code: = "�Lucida Sans�, �Lucida Grande�, �Lucida Sans Unicode�, Arial, sans-serif; !important";

That is just a few lines from the bottom of the xero.js file. I recommend replacing the line in question with this: = "Lucida Sans, Lucida Grande, Lucida Sans Unicode, Arial, sans-serif; !important";

@Jarret Minkler: What would you use instead of jQuery? Prototype? Mootools? No thanks...

Hi, I can fix it now. Please send me FTP details and wp-admin login by a private message.


Victor Teixeira answers:

You are loading jquery twice.
The theme is registering jquery again.

You don't need this.

Also take a look in all those jquery plugins included, you really need these?

Simple answer .. stop using jQuery, you'll be much happier you did.
