Laravel 4:2年后的白色屏幕

I didn't touched my personal website since 2 years and suddenly I have only a white screen with a Internal Server Error message in the console. That's it!

The website is build on top of Laravel 4.

I've wrote to my hosting service but apparently: hosting side is completely normal.

Any idea is appreciated, thanks!

Last error log

require(paths.php) [<a href='function.require'>function.require</a>]: failed to open stream: No such file or directory in /public/index.php on line 24

UPDATE

Ok I google it a lot and then I found out that there is a Laravel function called yield() that collides with a reserved name in PHP 5.5 that was not in PHP 5.4.

Any ideas?

Ok, got it!

The problem so is the conflict between the yield in php5.4 and php5.5 so in this link you know where you need to change yield to _yield to fix that without rebuild your entire site with another version of Laravel.
