Hi Emmy!
Thanks for reaching out although I’m sorry to hear you’re having trouble loading your BoldGrid Post and Page Builder editor.
This is most likely tied to your server migration and it would probably be best to give it some time and check it out after things completely propagate. One thing you can do is try removing your BoldGrid Plugins and then reinstalling and activating them.
Also when you switch to your chrome browser tools, do you see any errors listed under the “Console” tab? If so please copy/paste the error message into the thread here so that we can have a look.
