I've followed the guide, by downloading v88, putting SoulMS into the folder and HS file in the HS update file, and went to settings and clicked save changes but it leads me to a site that says "404 Error not found" on the top and the site says
"Not Found
The requested URL /fixhs/ was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
In black writing and just a white backround. I'm confused
