Until some time ago, it was necessary to hack the eZ Publish legacy kernel in order to customize its generic error message, "Fatal error: The web server did not finish its request". This error occurs on all eZ Publish installations whenever there is an HTTP 500 status server error. It is a very common error; some examples of how it's triggered include: trying to access the value of a non-existent object attribute; the use of a non-existent PHP class or function; and too much memory usage.
Now, since this pull request from Mugo has been merged to the eZ Publish kernel, we have made it possible to customize the error page without hacking the kernel. In this post I will show you the new standard way to do this with a simple INI setting and your own PHP function.
