[SOLVED] Towny Troubles

Okay. I really don't know what's going on here. I had someone raid my house today. Now, see, I'm the server owner, and have Towny installed. My house was raided in my town, and a buddy of mine saw someone do it. LONG STORY SHORT, people who aren't in my town can destroy blocks in my town, and can pretty much do whatever they want. I don't understand what I'm doing wrong here. Is it in my permissions file for default players?

Default player's permissions:

I've been trying to debug this myself, but can't seem to find the error.

Someone help?

Thanks,

UPDATE:
The problem was in my plot permissions. It's been fixed. Thanks for your suggestions.
