Hi @arsah , thanks for reaching out.
I tested IP-blocking on my end, and it is working as expected. Did you block the IP via the Wordfence > Firewall > Blocking > IP Address section?
If so, can you please confirm that you have blocked your public-facing IP address? It should be the same as the IP listed here – https://whatsmyip.com/ on the device you’re using to access the site.
If your IP address is blocked, you should see a Wordfence “Manual Block by Administrator” blocking page when you access the site.
You could also try clearing the cache on your browser or adding a cache-busting string to the end of the URL, such as /?no=cache, as you may be viewing a cached page.
Let me know how it goes.
Thanks,
Mark
