Hello and welcome to the forums,
Would you mind sending over links to pages/events displaying issues? I’d be happy to take a look and give it my best shot. I do want to point out that these types of conflicts are unfortunately outside the scope we’re able to support. I did a quick check on our logged bug reports and didn’t see anything pertaining to the Visual Composer.
Do any errors display when you set ‘wp_debug’ to true? For information on how to do so, visit this link: http://codex.wordpress.org/Debugging_in_WordPress
Keep me updated and thank you for reaching out. Enjoy the rest of your day.
Cheers!
