I just installed WP Super Cache, literally hours ago. It’s working for us here here (I think, anyway), but you got me thinking about what I’d do in your situation. If you’re using the Wordfence firewall put it in learning mode and try again, you might get prompted to whitelist what you’re doing, problem solved. Beyond that, I’d tend to just disable the firewall entirely as a trouble shooting step. The firewall is a good concept but frankly doesn’t seem to be all that necessary minute by minute. I’ve gone the whole month of July now without it blocking one thing and the site I watch it on the most is fairly high traffic.
Apologies to syop if I’m alluding to anything Premium. I don’t run the unpaid version so I’m not clear on what part of the Firewall is Premium and what is not.
