I just upgraded to the latest version of WPSC right now. But the problem I found is that when I click the button "Preload Cache Now" on page of "Preload", it says to rebuild the super cache files but after about 30 minutes, the super cache files are not generated.
Instead, if you open a webpage in the browser, the webpage then is generated in the supercache dir.
What can I do?
Here is the debug info I got:
No wp-cache file exists. Must generate a new one.
