app.php在symfony2.3中不起作用

Question

I create a symfony 2.3 project. some times all the pages shows 500 error. app.php also shows error. i dont know why can any one help

www.dotcue.in/sandp/web/app.php [HTTP/1.0 500 Internal Server Error 353ms]

Answer 1

I'm going to take a wild stab in the dark here and conclude that it is one of the following problems:

1. The prod cache is out of date, to fix it run: php app/console --env=prod cache:clear

2. The vendors are missing, to fix it run: php composer.phar install

If it is a problem when code that you have written however, we need to see the errors.

Answer 2

Too much HTTP headers (ex 4 kB) can cause this error depending on the hosting server. ChromePHP sends all of its data in HTTP headers. (you wrote you use ChromePHP)

Try turning it off or lowering the data sent with ChromePHP. Did it help?
