Adblock Plus

Hi, I've had no problems with this app until now, but basically I have Block all ads selected from within the app but for no reason it keeps randomly switching between allowing all ads and blocking all ads! As you can imagine this is very frustrating. I have tried un installing the app and reinstalling but without any luck, can anyone help me.

Having the same problem on my rooted Nexus 9 with Chrome. While reading a page it'll block the ads, load the next page in a forum and the ads are there, load the next and they might be gone.
