Problem with GriefPrevention

Ok so players in my server can't break any blocks on the server unless the part of their claim. Could you please tell me how to fix this issue ASAP.

Here's an image

People on my server are saying that whenever they claim with the goldenshovel they can't interact with anything other than what's in their claims.

 

@Complexinq
That is one of the feature of grief prevention. Have you looked in your config to see if you can turn it off?

 

How can I look at my config?

1. Go to the plugin folder.
2. Go to the GreifProtection folder.
3. Look for the config.yml
4. Scroll through the config and look for settings that may cause this problem. If you do not know what to look for/ how to look for those settings, post the fill config here (remember to use the code tags.)
