Pages not automatically caching

Hey everyone. I’ve been using W3 for a while now, and am having a slight issue with pages being automatically cached.

Somehow, it was disabled so I enabled it and emptied the cache. I have set update interval to 20 seconds and to limit to 10 pages per batch, but none of the pages have been cached when I go back a few minutes later. I have put a sitemap on there, and when I checked the second page down, it took a couple of seconds too long to load.

I am using basic disk checking, but it’s quite annoying as I have to visit the pages to get the cache served, when before it would automatically cache them.

It’s also serving old pages sometimes, but I’m not too fussed about that right now.

Any ideas?
