Hi,

Please can someone help me with this error :

I am using the sociallocker (https://codecanyon.net/item/social-locker-for-wordpress/3667715 ) website and I’m getting this error message :

Uncaught TypeError: $(…).sociallocker is not a function

here is the code :

page_js = " jQuery(function () {
‘use strict’;
blog.ItemDetails($);

    jQuery(document).ready(function ($) {
        $('#dst-social-lock').sociallocker({
            url: '".get_the_permalink($product->id)."?utm_source=ShareButton',
            theme: 'flat',
            facebook:{
                appId: '".get_option('dst-facebook-api')."',
            },
            twitter: {
                 tweet: {
                     text: 'Free download ".$product->title." by ".$user->userName." on @blog #blog'
                 }
            },
            text: {
                message: 'Share and download this product free.'
            },
            buttons:{
                order: ['facebook-share','twitter-tweet','linkedin-share'],
                counters: false,
                lazy: true,
                localStorage: false,
                console: false
            }
        });
    });
});

";
wp_add_inline_script(‘dst-script’, $page_js);

Thanks in advance
