What is Version Control in a CMS?

Version control in a CMS allows you to track and manage changes made to content over time. It enables users to:

• Review previous edits and changes.

• Restore older versions if mistakes are made.

• Track who made changes and when.

• Prevent accidental content loss.

Pro Tip: Version control ensures that no content is lost due to accidental edits or deletions.
