Visual Composer Frontend loading issue

Hi everyone,

I have recently inherited my company’s website & am totally new to all of this.

When trying to edit one of our pages by using Visual Composer, it just seems to get stuck with the icon “loading”. I think that this might have something to do with the fact that I updated the version of WordPress & quite a few plugins the other day…

Does anyone have any suggestions? (That aren’t too complicated!) I have tried to follow other people’s advice in other forums but am struggling & finding it all rather frustrating.

Thanks!
