Whenever I click Alert Checks from the global dropdown menu, an empty white page is displayed.   This was working before, and (unfortunately) I’m not certain when it stopped. I know It’s not related to any recent updates, as it’s been this way for a few months now. We just haven’t had time to investigate it further.   Example URL: http://obsevium.testing.local/alert_checks/ [http://obsevium.testing.local/alert_checks/]   I’ve renamed the following files in hopes that it was a simple corruption issue. However, the issue still persists.   $ sudo svn update && php discovery.php –u   Restored 'html/pages/alert_log.inc.php' Restored 'html/pages/alert_checks.inc.php' Restored 'html/pages/alerts.inc.php' Restored 'html/pages/alert_check.inc.php' At revision 6859.   -- Database is up to date.   Has anyone seen this before? I’d be more than happy to provide additional debug output.     Images:                     Thank you.   Nate Mellendorf | Network Analyst | Netgain 720 West Saint Germain Street | St. Cloud | MN | 56301 Phone: 320.251.4700 x183 | 877.797.4700 x183 www.NetgainHosting.com [http://www.netgainhosting.com/]
