I haven't work on my project Laravel 4 for about 2 days now, and I don't think I make any changes to my code or database, when I land on a homepage, I no longer see my homepage.

I start to see this instead

/vendor/laravel/framework/src/Illuminate/Session/Store.php

Question

How would one go about and debug this ?

I'm opening to any suggestions at this moment.

Any hints / suggestions / helps on this be will be much appreciated !
