I've installe a new system Centos 6.3, then installed apache, git, php, mysql. I then followed both guides and whith each one when going to web pages I get Fatal error: Exception thrown without a stack frame in Unknown on line 0.
Most common cause for it is a fatal error or an exception in an object __destruct() method (the framework itself doesn't use those), or in a shutdown handler, or an exception in the exception handler.
Errors should be logged in the webserver error log, so maybe you can start your search there.
Ok, resolved issue. It was because timezone wasn't set in php.ini. Shame the error didn't indicate that! Anyway that should save someone a few hours of searching online as there isn't much out there about this!
