Final answer:
To preview in the CMS, you may need to disable the caching system to ensure the most recent version of the content is displayed.
Step-by-step explanation:
In order to preview in the CMS, you may need to disable the caching system. Caching is a mechanism used to store copies of web pages or other types of web content, which can improve performance by serving the stored copies instead of generating them each time. However, when making changes to the content, the cache may not reflect the updates, resulting in an inaccurate preview.
By disabling the caching system, you ensure that the preview displays the most recent version of the content you are working on in the CMS.
