Think I've got a couple bugs...
I've used WP Super Cache for quite some time now, never had a problem, it's always worked great, until the last version or two. I've got two issues with it and I've seen the same thing across several other sites/hosts for people I help support.
First Super Cache does not seem to work now with GZ Compression, or at least it reports it as a WP Cache page. Rather than getting:
<!-- super cache gz -->
Can only ever get:
<!-- Cached page served by WP-Super-Cache -->
<!-- Compression = gzip -->
Also, cached pages do not seem to be naturally expiring/refreshing. So if you go to the previous post, up to a couple days, there will be no next button. This is with the default 3600 second setting. I've gone ahead and forced cache clearing on posting.
Others seeing this too?
