VPN Unlimited tells my my browser doesn't accept cookies
After installing the latest Security and Safari updates, I get an error when logging in to VPN Unlimited telling me that my browser doesn't accept cookies. But my Safari DOES accept cookies. What's the deal? I reset my cookie settings, rebooted several times, and even uninstalled and reinstalled VPN Unlimited.
