Hey Amin,
Thanks for reaching out.
Our plugins do not have any special support for Visual Composer, but there are not other reports of this specific issue….
I see in your System Information—thanks for sharing it!—that you’re using the most recent version of all of our software, so that’s not an issue here. There may be a code conflict—to help reveal if this is the case, do any errors pop up on your site if you head to your site’s wp-config.php file and change this line of code:
define('WP_DEBUG', false);
to this:
define('WP_DEBUG', true);
That will display PHP errors if any exist, which might be quite useful here.
In the meantime I would also recommend opening a support ticket with the Visual Composer folks if you haven’t done so already.
Let us know what you find!
George
