You asked if I had any new extensions. I do but I have disabled most of the blockers because of this problem. But I still have Wipr and Porn Block activated. Maybe it's Wipr? Ghostery, adblock plus, etc., are all disabled and I still get the problem. I don't have the Wipr or porn block (that shouldn't be it) on Firefox. So maybe it's narrowed down to those two. Let's see.... On wow, guess what? When I disabled porn block, I was able to get onto Imgur!!! LOL!
Some sites say they can see a content blocker and ask that I disable it. Others don't. It's just Safari that lets me know and I can't get in. It looks like more and more sites won't let us on with content blockers even though they don't always say so. It's funny that I can get in via Firefox though. I need to check when I get a chance and see what blockers I have on Safari that I don't have on Firefox and find the culprit that way maybe. Phooey!
I don't recall ever running into an error message such as yours.
I use Safari exclusively, and any time I can't get into a site because of AdBlock I get a pop-up from the site itself (at which point I reevaluate how badly I actually
want to get into the site).
