Thanks for the system report. Nothing in it stands out as an obvious issue.

Are you getting this 403 error only for some of your child sites?

Can you try performing a scan of one of your affected child sites directly on Sucuri’s site https://sitecheck.sucuri.net/?

Hey Bojan,

The error appears on all child pages. And the direct check on the Sucuri website works without error.

Thanks for trying that.

Would you mind opening a private Help Desk ticket so we can collect some additional information & investigate further?

And please refer to this Managers thread by its URL in the ticket.

Done. Thanks for your help!
