Proxy Logs Empty

I’ve enabled the transparent proxy on green and blue with ClamAV, URL filter and update accelerator enabled, but I don’t see any entries in the proxy log. I don’t have an upstream proxy listed and everything below the cache settings is left as default. I’m assuming it’s not proxy-ing anything. Can someone point me in the right direction? I’ve added a snapshot of the cache management thinking that might be the problem. I’m running an Intel Celeron 4-core, 64-bit box with 4GB RAM and 8GB Storage that serves an average of 12 users.

Seems to have been just a web page glitch. Using Chrome, the logs didn’t show when I first navigated to the page. However, when I clicked on the little back and forth arrows to move to a different day and then back to today, the log appeared.
