Reproduction Steps

Course Builder

1. Install any plugin that provides object caching (The customer was using Object Cache Pro (MU)).
2. Open the Course Builder and make any changes.
3. The Save button doesn't get activated nor does the automated save run while Object Caching is enabled.

Default Lessons Blocks

1. Install any plugin that provides object caching (The customer was using Object Cache Pro (MU)).
2. Open an existing lesson with all the default blocks (Lesson Progression, Lesson Navigation.. etc.).
3. Once opened in the editor, it removes all the default blocks both in the editor and frontend.
4. And it also removes the blocks when creating any new lesson.

Expected Behavior

Course Builder

The Save button should work as expected. It should get enabled or save changes automatically after every change.

Default Lessons Blocks

The blocks shouldn't get removed when opening the existing lessons or creating new lessons by using the Gutenberg editor.

Install any plugin that provides object caching

Which other plugin did you test?

@eri-trabiccolo

I tested the LiteSpeed Cache. You can find the object caching settings in the LiteSpeed Cache setting in the dashboard.
