404 error is from these <img src=":large" class="vc_gitem-zone-img" alt=""> It seems they are from some post grids from WPBakery.
As for JavaScript error, I suppose it come from content also, but it can be caused by some embed, as this script is for processing WordPress embeds(Video for YT, VImeo, Tweets form twitter, etc).
