UPDATE:
Found the issue causing this problem for you guys. Remove www. in front of the URL. I will push an update to fix this ASAP. The filter was a bit too strict.

EDIT:
Okay guys, the issue is fixed. I just pushed version: 1.0.1 to the chrome store. (it should be ready for everyone in a maximum of 60min.) Please update your extension if it isn't done automatically.
