symfony - 500 error page customisation problem

I am ready to push a site to production (currently on staging), but I'm having a slight problem with the internal server error 500 page.

I have created a file in web/errors/error500.php and I've also got: ErrorDocument 500 errors/error500.php in my .htaccess file

The problem is, if there is a 500 error in the admin, it displays the symfony default 500 page instead of mine in the errors folder.

Does anyone have a rough idea why this is?

I've cleared symfony cache, cleared开发者_运维技巧 browser cache and used several browsers.

Thanks

The standard Symfony way of doing this isn't with an Apache ErrorDocument directive, but simply by putting your error page in either <project>/apps/<appname>/config/error/error.html.php or <project>/config/error/error.html.php, for per-app or general error pages respectively. See this checklist item on the very handy Symfony Deployment Cheat Sheet.

Also make sure you are not in debug mode when you test this otherwise it will still show full stack trace.
