Hi! Have you been able to resolve the issue? If not, please share a screenshot of the Activity log showing the blocked requests so we can better understand why they were blocked.
You can also use the new diagnostic tool on the Activity log page. To figure out the reason why WP Cerber blocked a REST API request, click the ellipsis (three dots) icon in the corresponding event row. This will show you detailed explanations, the specific security settings WP Cerber applied to the request, and possible actions you can take.
