When attempting to visit the Status > RRD Graphs page of pfSense, I am greeted with a blank page... Most likely due to PHP being unable to complete the request...

I am unsure how to repair this. On Linux I would usually run something akin to the following to discover the problem, but I can't do this on pfSense (AFAIK):

su -l apache -c 'strace php /usr/local/www/status_rrd_graph.php'

Any theories?

Just to demonstrate how little is returned by PHP:

$ wget https://XXX.XXX.XXX.XXX/status_rrd_graph.php --no-check-certificate -O -

It's returning a 200 code so it has at least output errors before crashing. –  DerfK Jul 21 '12 at 18:08

Hm, first I've heard of that happening. A quick fix should be to apply the update for the version you're already running, which will basically reinstall the system (overwrites all the system's files at least).

Unfortunately, that did not work... I applied the update image found here: files.chi.pfsense.org/mirror/updates/…, using the web UI (System > Firmware > Manual Update). And after bit of downtime, the RRD screen is still unavailable... –  Soviero Jul 22 '12 at 6:02
    
Never mind, that was a false-negative. The empty page was cached, after clearing the cache, everything works on the RRD Graphs page... Thank you! –  Soviero Jul 22 '12 at 6:09
