White screens are usually caused by a fatal error between execution
filter and render filter.
If you can reproduce the error on a local development machine, I'd
suggest installing sfErrorHandlerPlugin and modifying the plugin so
that it shows you the error when not using the dev controller. Don't
do this on a live server - you'll see too many errors for it to be
acceptable.
Change line 71 of sfErrorHandler.class.php :
Was : if (!sfConfig::get('sf_debug'))
To : if (sfConfig::get('sf_debug'))
You'd probably want to change line 50 of
sfHardenedRenderingFilter.class.php :
Was : set_error_handler(array("sfErrorHandler",
"error_handler"), sfConfig::get('sf_error_reporting', E_ALL &
~E_NOTICE & ~E_WARN));
To: set_error_handler(array("sfErrorHandler",
"error_handler"), E_ALL & ~E_NOTICE & ~E_WARN);
That should give you a little more to go on - I expect you'll find
it's an uncaught exception being thrown somewhere, or a 3rd party
library causing a fatal error. If it's either of those, it should
manifest itself as an sfLegacyErrorException.
HTH :)
