Hi Rikard, Thank you. Sucuri is a separate malware monitoring service, not a plugin. It is not easy to turn on and off. Are you sure you cannot login in anyway? What is the error or problem?

Please email/CC (Email address hidden if logged out) so I can see when you reply, otherwise I am not notified and it causes a long delay in my ability to reply to you.
Thank you. I appreciate your help.
