If you are using Blue.box to configure your FreeSWITCH softswitch then blue.box uses Kohana 2.3 and this has a quirk with PHP 5.4 which means that you will end up with a blank page (even after a clean git pull) plus a spurious array to string conversion error.
For the BLANK screen issue then the fix is,
See https://gist.github.com/kemo/2881489 for a working fix. Note that that patch isn’t exactly lined up on the line numbers – my git diff is,

For the array to string conversion error you see the sort of useful orange trace back Kohana error page and this,
An error was detected which prevented the loading of this page. If this problem persists, please contact the website administrator. bluebox/libraries/doctrine/lib/Doctrine/Query/Abstract.php [1103]: Array to string conversion
To fix this you need to do changes to Abstract.php and Lib.php which is basically making a new function arrayDiffSimple and then adding that new function to the Lib.php.
