Cloudflare and WP Cerber
How to make them play nice together on your WordPress
If your site is behind the Cloudflare proxy service and your WordPress is protected by the WP Cerber plugin, you have to do two things to let them work well together.
- Enable My site is behind a reverse proxy on the Main Settings page.
- If you have configured the Custom login URL, you have to exclude it from caching by Cloudflare’s servers. Do that by adding a rule on the Page Rules settings page in your Cloudflare account settings as described here: https://support.cloudflare.com/hc/en-us/articles/200172316-How-do-I-exclude-a-specific-URL-from-CloudFlare-s-caching-
Integration with the Cloudflare firewall
Consider using an optional Cloudflare add-on to synchronize locked out malicious IP addresses and access-lists entries with the Cloudflare cloud-based firewall.
