Nagios Support Forum

seems like mv /usr/local/nagiosxi/html/includes/components/nagiosim /tmp/ fixed the issue,
It just took a little bit of time for the issue to go away.

And yes it was right after the upgrade.

You can go ahead and lock this.

Glad to hear it is resolved. I am going to lock the thread. Please feel free to post again if you have you another issue. Thank you for using the Nagios forums!
