If you use the “revert changes” function in the Onsite Optimiser, the changes will revert back to the original as set up in your CMS platform.
So for instance, if you have a H1 heading you’ve edited and updated a few times in the Onsite Optimiser, and select revert changes, the changes will be as they were in your CMS and not as they were in your last Onsite Optimiser session.
Once changes have been reverted, this cannot be reversed.
