Thanks for your reply, however I may not have explained my issue very well.
I have a VPS and have setup a website and installed Swift Performance Lite.
I have run the Auto Config (and tried presets etc)
In the prebuild section I have 164 pages that are “Known”
If I click “Start Prebuild” it will cycle through the pages but not actually cache them, If I click them manually it will not actually cache them
I have tried setting the server to Pure Nginx & Ngix + Apache and have enabled the rewrites in the nginx conf file
I really like this plugin when it works, and I really want to get the Pro version, but will only do this when I have got the free version working
