Hi there,
Ensure everything is up to date according to our version compatibility list here. Please follow the best practices when updating your theme and plugins. Click here for more information.
Then please kindly add the Javascript code below to X > Launch > Options > JS:
jQuery( function($) {
$('.vc_tta-tab a').on('click', function( e ){
setTimeout( function() {
$('html, body').stop().stop();
}, 100 );
});
$(document).ready(function() {
$('.vc_tta.vc_general .vc_tta-panel-title > a, .vc_tta.vc_general .vc_tta-panel-title > a, .vc_tta-tab a').off('click touchstart touchend');
});
});
If you still have the problem regarding the Visual Composer Tab scrolling, you will need to upload your website to a live server and give us the information to be able to see the live code.
Thank you.
