Breaks Customizer

This plugin has broken access to the Customizer. Attempting to load the Customizer instead loads an unstyled widget edit page for the widget. Hello, I can’t seem to replicate the issue you are experiencing. We’re there any errors in your javascript console? (⌘ + Option + j). Thank you No there are no errors in the console. This is occurring on a multisite instance. The screen that loads is only a snippet of html: <div id='widget-21_wp_subscribe-__i__' class='widget'> <div class="widget-top"> <div class="widget-title-action"> <button type="button" class="widget-action hide-if-no-js" aria-expanded="false"> <span class="screen-reader-text">Edit widget: WP Subscribe Widget</span> <span class="toggle-indicator" aria-hidden="true"></span> </button> <a class="widget-control-edit hide-if-js" href="/wp-admin/customize.php?return=%2Fwp-admin%2Fplugins.php%3Fplugin_status%3Dall%26paged%3D1%26s&editwidget=wp_subscribe-1&addnew=1&num=2&base=wp_subscribe"> <span class="edit">Edit</span> <span class="add">Add</span> <span class="screen-reader-text">WP Subscribe Widget</span> </a> </div> <div class="widget-title"><h3>WP Subscribe Widget<span class="in-widget-title"></span></h3></div> </div> <div class="widget-inside"> <div class="form"> <div class="widget-content"> <div class="wp_subscribe_options_form"> <!-- Hidden title field to prevent WP picking up Title Color field as widget title --> <input type="hidden" value="" id="widget-wp_subscribe-__i__-title" name="widget-wp_subscribe[__i__][title]"> <div class="wp-subscribe-label-field wp-subscribe-service-field"> <label for="widget-wp_subscribe-__i__-service"> Service: </label> <div class="wps-input-wrapper"> <select class="widefat list-selectbox" id="widget-wp_subscribe-__i__-service" name="widget-wp_subscribe[__i__][service]"> <option value="aweber"> Aweber </option> <option value="feedburner" selected='selected'> FeedBurner </option> <option value="mailchimp"> MailChimp </option> </select> </div> </div> <div class="wp_subscribe_account_details"> <div class="wps-account-details wp_subscribe_account_details_aweber" data-service="aweber" style="display: none;"> <div class="aweber_authorization_area mb30"> <strong>To connect your Aweber account:</strong> <br /> <ul> <li><span>1.</span> <a href="https://auth.aweber.com/1.0/oauth/authorize_app/1afc783e" target="_blank">Click here</a> <span>to open the authorization page and log in.</span></li> <li><span>2.</span> Copy and paste the authorization code in the field below.</li> </ul> <textarea rows="4" cols="80"></textarea> <br /> <button type="button" class="button-primary aweber_authorization">Authorize</button> </div> <div class="alert alert-hint mb30 hidden"> <p> <strong>Your Aweber Account is connected.</strong> <a href="#" class="aweber_disconnect">Click here</a> <span>to disconnect.</span> </p> </div> <input id="widget-wp_subscribe-__i__-aweber_consumer_key" name="widget-wp_subscribe[__i__][aweber_consumer_key]" type="hidden" value=""data-id="aweber_consumer_key"> <input id="widget-wp_subscribe-__i__-aweber_consumer_secret" name="widget-wp_subscribe[__i__][aweber_consumer_secret]" type="hidden" value=""data-id="aweber_consumer_secret"> <input id="widget-wp_subscribe-__i__-aweber_access_key" name="widget-wp_subscribe[__i__][aweber_access_key]" type="hidden" value=""data-id="aweber_access_key"> <input id="widget-wp_subscribe-__i__-aweber_access_secret" name="widget-wp_subscribe[__i__][aweber_access_secret]" type="hidden" value=""data-id="aweber_access_secret"> <input id="widget-wp_subscribe-__i__-aweber_account_id" name="widget-wp_subscribe[__i__][aweber_account_id]" type="hidden" value=""data-id="aweber_account_id"> <div class="wp-subscribe-label-field wp-subscribe-aweber_list_id-field"> <label for="widget-wp_subscribe-__i__-aweber_list_id"> AWeber List </label> <div class="wps-input-wrapper"> <select class="widefat list-selectbox" id="widget-wp_subscribe-__i__-aweber_list_id" name="widget-wp_subscribe[__i__][aweber_list_id]"> <option value="none"> Select List </option> </select> <button class="button wps-get-list">Get list</button> </div> </div> </div><!-- /wp_subscribe_account_details_aweber --> <div class="wps-account-details wp_subscribe_account_details_feedburner" data-service="feedburner" style="display: none;"> <div class="wp-subscribe-label-field wp-subscribe-feedburner_id-field"> <label for="widget-wp_subscribe-__i__-feedburner_id"> Feedburner ID </label> <div class="wps-input-wrapper"> <input class="widefat" id="widget-wp_subscribe-__i__-feedburner_id" name="widget-wp_subscribe[__i__][feedburner_id]" type="text" value=""data-id="feedburner_id"> </div> </div> </div><!-- /wp_subscribe_account_details_feedburner --> <div class="wps-account-details wp_subscribe_account_details_mailchimp" data-service="mailchimp" style="display: none;"> I also have problems! When I go to Apperence – Customize I get this screen Edit widget: WP Subscribe Widget Edit Add WP Subscribe Widget WP Subscribe Widget Service: It´s works if I deactivate your program. Hello, Please let us know which versions of WordPress and PHP you are using so that we can try to replicate the issue on our end. Thank you. I’m running 4.8.1 of WP in multisite mode and 1.2.3 of your plugin. PHP is at 5.3.3. Thanks!
