I had to reinstall the AdBlocker plug-in, so it must've reset all the settings to default. Should be back to how it was now.
Every page you view on here costs money to serve though, and with a lot of people evidently using AdBlocker it's not sustainable in the long run. It threatens the long term future of the site. If you are willing to turn AdBlocker off for this site then it would be greatly appreciated. The issues we had with the "Congratulations! You have won..." pop-ups are resolved now so you should only see regular ads.
Someone mentioned a subscription fee for those who don't want to see ads, so will look into whether or not that's a feasible alternative.
