When I try to use the Flexslider with 'built-in' jquery, the Flexslider won't work. When I use my own **myjquery** file, It works as if nothing ever. Do I always have to use my own jquery file even wordpress has its own? - Wordpress' (built in) jQuery vserion: 1.11.3 - Flexbox required jQuery version: 1.7+ - **myjquery** = jquery version: 1.12.0 Summary: flexbox should work with jQuery of WordPress. ------------ ### Briefly Flexslider doesn't work when I use Wordpress' jQuery. It works when I add my own **myjquery.js** which is jquery 1.12.0 and when I dequeue original jquery `wp_dequeue_script('jquery');`. It looks like WordPress' jQuery is not visible for my Flexslider and custom.js file. Errors: When I run the site with WordPress with its own jQuery there is one error: `$ is not a function` file: 'custom.js:2:1' what means that jquery is not found but it's included in header (I've checked). _When I use 'myjquery' there is no errors and plugin works correctly._ The content of 'custom.js': ``` $(window).load(function() { $('.flexslider').flexslider({ animation: "slide" }); }); ``` -------- Register and include styles & scripts: wp_register_script( 'bootstrap-js', get_template_directory_uri() . '/bootstrap/js/bootstrap.js' ); wp_register_script( 'myjquery', get_template_directory_uri() . '/js/jquery.js' ); wp_register_script( 'flexslider', get_template_directory_uri() . '/js/flexslider.js', array('jquery'), false, true ); wp_register_script( 'custom-js', get_template_directory_uri() . '/js/custom.js', array('flexslider'), false, true ); // Enqueue :: styles & scripts function mytheme_enqueue_items() { wp_enqueue_style( 'my-main-css' ); wp_enqueue_style( 'bootstrap-css' ); wp_enqueue_style( 'bootstrap-responsive' ); wp_enqueue_style( 'flexslider-css' ); // wp_enqueue_script( '**myjquery**' ); // **flexslider works correctly when uncommented** wp_enqueue_script( 'bootstrap-js' ); wp_enqueue_script( 'flexslider' ); wp_enqueue_script( 'custom-js' ); } add_action( 'wp_enqueue_scripts', 'mytheme_enqueue_items' );
