Check for plugin conflicts
If Your Running SEO Ultimate or Yoast try deactivating them and see if yjat works. It did for us on over 14 sites
@inflac did you see what i posted above yours it might help.
Hey everyone, on my sites we found that seo ultimate plugin was active and caused a conflict with wp bakery after the 5.5 update. I checked another site we work on that was not running that or Yoast which has been a problem before as well and that site was working fine after the update.
