Hey Susan,
Do you mean the files are still showing under the wp-contents folder or the menu is still showing on your site?
If you mean the files are still showing and you are referring to the Free plugin, then this is all handled by WordPress themselves so there will be an issue with your WordPress configuration.
If you are referring to it still showing on your website then please provide a link to your site as I don’t have anything to look at unfortunately.
Also, please confirm you don’t have any caching plugins installed or any server caches etc.
If you do have any caching, please clear those and it will disappear.
All the best
Peter
