I’m also getting this error:
Warning: Missing argument 3 for Livemesh_VC_Addons::custom_css_classes_for_vc_row() in /home/seilersingleton/public_html/wp-content/plugins/addons-for-visual-composer/livemesh-vc-addons.php on line 280
I’ve updated the livemesh-vc-addons.php per the suggestion above, and confirmed that I’m using the latest VC version (4.11.2).
The theme I’m using is Broker with WordPress version 4.5.1.
