Hi Satomi,
This is a 'bug' in APM that will be fixed in a next release.
Under Settings>Enabled (on the APM Manager) your setting is probably "Runtime agent + Browser agent without guests" or "Runtime agent only", so when an Annonymous user accesses the page it shows that the Browser agent is disabled, but this shouldn't be shown as an error of course. In a next release it won't be shown as an error.
Issue is fixed

Hi Satomi,
I think it would be best if you contact Mendix support for issues with APM.
