@drrichbunk Just wanted to say thanks for your suggestion.
My client also wanted a newer jQuery version for security. So we updated it using jQuery Updater plugin, because it’s safe and doesn’t replace the WP core’s jQuery version, hence never suspected a thing… It actually worked fine for like a day, so we though it’s one of the new plugins.
Simply deactivating the plugin solved the issue and the Divi visual builder stopped showing the:
et_pb_section could not be displayed.
hide error message
TypeError: Cannot read property ‘TagName’ of undefined
