I'm having a really weird problem with WP Super Cache. It's generating the cache directories and files. I can see them there, and when I download the actual files (both html and gzip) I can see the time stamp at the bottom.
But, when the pages are served, there's no timestamp. The built in cache test fails as well. But, oddly enough there are a few blank lines at the bottom of the source of the cached pages, like where the timestamp would be.
Also, I can generate the cache for two specific category pages, and I can see the time stamp in the source for those. I've tried it a couple times and it's consistent.
I've also reinstalled WP Super Cache, disabled all other plugins, and tried from a few different browsers with cookies cleared.
Any chance the cache files are being served, but I'm just not seeing the time stamp at the bottom for some reason? I'm really at a loss, so any help is appreciated.
