Reporting a Bug

Whenever you find a bug in Symfony, we kindly ask you to report it. It helps us make a better Symfony.


If you think you’ve found a security issue, please use the special procedure instead.

Before submitting a bug:

If your problem definitely looks like a bug, report it using the official bug tracker and follow some basic rules:

  • Use the title field to clearly describe the issue;
  • Describe the steps needed to reproduce the bug with short code examples (providing a unit test that illustrates the bug is best);
  • If the bug you experienced affects more than one layer, providing a simple failing unit test may not be sufficient. In this case, please fork the Symfony Standard Edition and reproduce your issue on a new branch;
  • Give as much detail as possible about your environment (OS, PHP version, Symfony version, enabled extensions, ...);
  • (optional) Attach a patch.
