I'm using Drupal 7.23 on my test site and since a couple of days the status report page is completely blank (no theme, no menu, nothing). No info shown at all. Other (report) pages are shown without noticeable issues.
Does anybody have an idea what could cause this? I have a almost similar 7.23 life site that shows this /admin/reports/status report perfectly.
Any log-file to check?
