When Nagios Core 3.2.3 came out, I waited a week to see if the main landing page (main.php) would tell me that an update was available. My notification never showed up. If everything is working properly, I THINK it is supposed to display a banner on the page that says "A new version of Nagios Core is available!".
I do have check_for_updates=1 and bare_update_check=0 in nagios.cfg
Also, as a test, I modified the main.php file so that the line that read \\$updateinfo['update_available']=true; was changed to $updateinfo['update_available']=true;
When I did that, the banner was displayed.
Can you give me some ideas on where I can start troubleshooting why none of my 3 Nagios servers is working?
