I just installed Super Cache and it seems to be working well as my web site is loading a lot faster.
However in the settings under Cache Contents I see:
WP-Cache (342.33 KB)
10 cached pages
1 expired page
WP-Super Cache (61.54 KB)
2 cached pages
0 expired pages
As far as I know, I followed all the installation instructions and deleted the cache config files as per the documentation, so am wondering if this is normal, i.e. to have these two different cache contents.
