使用app.php的Symfony错误500，在app_dev.php上运行正常

Question

I am currently trying to use our (basic) Symfony 2 app by accessing app.php. However, whenever I try to access app.php, I get an error 500. I have checked the logs, the production log is empty. I have tried the assetic entry in the config file, but to no avail. Anyone else who has any ideas on how to fix this?

This is a very basic application (for now), with just some routing changes and a new controller. The most part is html (as a test), so it can't be the php we've written so far.

--edit: I currently do not have the documentroot pointing to the /web directory, but I don't have admin rights on the server. However, because the app works in app_dev.php, I don't see how this could be a problem?

Answer 1

The problem also can be caused by changing state of one variable into the web/app.php file from false to true .

Check linie:

$kernel = new AppKernel('prod', false);

and change to:

$kernel = new AppKernel('prod', true);

Answer 2

I had the same issue, but with setting true:

$kernel = new AppKernel('prod', true); 

I managed to get a readable error message. In my case there was a problem with an mysql-table.

Answer 3

我通过从我的.yml配置文件中删除一个选项卡并联系serveradmin来将其修改为/ web。

Answer 4

它可能有点晚了，但我今天得到了同样的错误，有助于清除缓存。

Answer 5

I ran into this issue today, and enabling debug mode through AppKernel still didn't show the error. Turned out I had enabled ApcClassLoader in app.php (just before AppKernel is initialized) but APC wasn't yet enabled on the new environment I deployed to. Commenting the APCClassLoader bit out again in app.php resolved the issue.
