Nagios Support Forum

Today when I try to access Nagios web console by "http://<ip address>" it leads to the welcome page. When I clicked on "Access Nagios XI" it leads me to a blank page "http://<ip address>/nagiosxi/". This was working last week and I don't know who could changed stuff on it. Thank you for your help.

Usually that blank page is due to MySQL db corruption, typically caused by an unclean VM shutdown. The following doc should help you out:

I'm still having the blank page. Here's an excerpt from putty log:
