Manually Clear WP Rocket Cache
If you need to manually clear the WP Rocket cache, you can do so using an FTP program, or the File Manager in your hosting control panel.
All your site’s cache files are stored here:
You will see sub-folders for each page, category etc and within those, an index.html and index.html_gzip for each.
So if you need to delete the entire site cache, just delete all folders files within the folder yourdomain.com.
Or you delete a specific page’s cache by deleting just that folder.
See the following video for a demonstration:
