Plugin blocking Google?

Hey guys, first, let me say that I absolutely love and appreciate this plugin. I wanted to bring something to your attention and see if maybe I did something wrong or if there is an issue with the plugin –

Today, we noticed that a site was getting multiple errors coming from Google. In checking Webmaster Tools, I found that Google was getting 403 errors on basically the entire site.

I couldn’t find anything that should be blocking Google, so I tried disabling AIOWPS, and sure enough, as soon as I did (and I made no other changes), Google was able to fetch the site again.

Any thoughts as to why/how this happened? Could I have a setting in there that caused this? Thanks in advance!
