(FYI this form does not allow you to submit something for MDB Builder because it clears the "MDB Version" field but it still requires that field to have a value.)

Expected behavior Builder site loads (https://mdb-builder.com/editor)

Actual behavior Builder displays loading spinners and never loads the actual tool.
