NOTE: If something has been deleted or a version removed, it can be restored from the Recycle Bin within the dashboard start menu from the Sitecore button:
Or by accessing the Recycle Bin from the Launchpad:
Once the Recycle Bin is open, an item/version can be selected and restored with the Restore button. When restored, the item will follow the included path and be restored at that point in the catalogs.
Please note:
Only items deleted by the logged-in user are visible to them in the Recycle Bin.
