ISC_ContentAdmins and ISC_ContentEditors can modify existing content revisions in Optimizely <<product-name>>.
Go to the entity where the content revision was made (that is a Product, Category, Specification, and so on)
Select the entity's **Content** finger tab.
Within the Content Manager section, select the latest unapproved/unpublished revision.
Modify the content in the content area field.
Only one unapproved, editable revision may exist at a time. To edit a previous revision, the current unapproved revision must either be approved/published or deleted, and then a new revision must be created based on the desired previous revision.
Click **Save** to save changes.
Once a revision has been Approved and Published, it cannot be modified. If changes need to be made, a new revision (based off the previous one) needs to be created and then edited.
