japiera Hi José Andrés,
I've been testing it through deactivating all plugins except of WooComemrce and Divi. Only, when ATUM is activated the issue is caused and Divi Theme Builder won't load properly. It load, when I deactivate ATUM, but that's not the solution for the workflow. It started around 2 weeks ago. I guess there is something going with the update. All plugins are updated. I already contacted the Divi support and they lead me to you.
I hope you can help me to fix it.
Best regards,
Vuong
