I have WP-SuperCache running and I see cached and expired stats in the admin screen but it is only caching pages on a particular category. The rest of the site is not cached.
In the pages that are cached (with WP Cache and Super Cache set to on) this text is added:
<!-- Dynamic page generated in <time> seconds. -->
<!-- Cached page generated by WP-Super-Cache on <date & time> -->
Same for Half ON mode.
We've known it's worked having run it on the site since inception but only recently has the site performance been in question and it was then we noticed that WSC was not actually caching all the pages we thought.
I can't find any option/configuration or setting that would make this happen.
Anyone have any ideas beyond the installation notes and FAQ or perhaps has experienced this and has a suggested resolution?
