Upgraded from 3.1.2 from 3.0.6 using the following instructions:
nagios.sourceforge.net/docs/3_0/ … l#nagios3x
Now I cannot access “http:///nagios” with localhost being the server where Nagios is installed.
When trying to access the site, it prompts to download the following file
unknown file format 768K
It seems it is [application/x-httpd-php] file.
