Thanks pvnanini and ivole for your comments. I spent a whole bunch of time trying to solve the problem of cusrev.com not being able to update my WordPress site. I’d narrowed it down to Cloudflare but even disabling my firewall rules didn’t work.

After reading this thread I re-visited the Cloudflare dashboard and found a firewall log entry for IP address 18.210.171.51. This showed that the connection was blocked not by a user-defined firewall rule, but by Cloudflare’s Bot fight mode (under Firewall \ Tools in the dashboard). Briefly disabling Bot fight mode allowed me to push a review from cusrev.com to my website, so confirmed that this was the cause of the problem.

My solution at Cloudflare then was to enable Bot Fight Mode again and then add an IP Access Rule under Firewall \ Tools to allow traffic from 18.210.171.51 to access all websites in my Cloudflare account. Note that this is done under Firewall \ Tools, not Firewall Rules. I’ve tested this again and it allows the reviews to pass from cusrev.com to my website.

Importing Reviews from cusrev.com to WordPress

Once the connection was working again, I imported the reviews that had previously failed to transfer from cusrev.com to my website, through the cusrev.com dashboard (https://www.cusrev.com/dashboard/reviews). You can see a failed message to the right of each review – I clicked the Woocommerce button to have it re-send the review to my website.

The reviews are imported to WordPress with the current date and time, so I edited the dates of each manually imported review (on my site) to match the date of the review at cusrev.com.

Hope this helps!
