To ensure a smooth transition to a new version of the Design Editor, follow our step-by-step instructions.

Missing Preloader

When you upgrade the Design Editor to version 4.0, the preloader does not appear in the Design Editor.

Solution

Design Editor 4.0 introduces breaking changes in the preloader feature. Now, you set up this feature through the preloader object in IConfiguration, which enables the preloader by default. So, if you already customized the preloader and want to keep your implementation, please set the preloader.enabled property to false when migrating from any 3.x.x release to 4.x.
