I have Wipr too but find I have to disable it on a lot of sites because it causes me problems. Same with Ghostery. And I'm too cheap to pay for Roadblock.
Neither Wipr nor Ghostery is causing your problems; it's just that websites have become more sophisticated and better able to pick up on ad blockers - no matter which variety - and block
them.
If you've got
the little gear wheel guy in your Safari menu bar you can uncheck the "Enable content blockers box" on a website by website basis to whitelist particular sites, and if you haven't got it, it's because your Safari is too far behind the times.
I caught Roadblock for 1/2 price around X-mas, but its functionality is so important to me that I'd have paid full price. As far as I've been able to tell, it's unique.
