This thread is resolved. Here is a description of the problem and solution.
Problem: I want to edit my website using divi builder but the page is white and I see an error in the console.
Solution: Deactivate all the plugins except for WPML (and its add-ons), and then activate them back one by one. This way you'll be able to identify what's the plugin that's causing this issue. WPML is compatible with Divi (https://wpml.org/theme/divi/) so this issue is caused by one of the other plugins used on the website.
