Hi there! Sorry for the delay.
1. My site is: https://www.AdventureWithoutEnd.com
2. I downloaded the plug in from this page (the wordpress plug in page)
3. I uploaded via FTP
4. I turned it on, and my site instantly reverted to plain text with no formatting, no photos, and no theme. Possibly this was due to a conflict with my theme? I run Flexibility Theme for WordPress: https://www.flexibilitytheme.com/
5. I have back-ups, but didn’t need them; as soon as I deactivated the plug-in, my site returned to normal.
