Enable developer mode using the CLI command `php bin/magento deploy:mode:set developer` as shown [here](http://devdocs.magento.com/guides/v2.0/config-guide/cli/config-cli-subcommands-mode.html#config-mode). — Steve Johnson, Jan 07 '16 at 15:02
Check the webserver's error_log, too. In hosting environments, it is normally written to a subfolder in `~/`. — Krista K, Jul 09 '19 at 20:33

Add following code in index.php file :-

error_reporting(E_ALL);
ini_set('display_errors', 1);

Setting developer mode does not makes fatal errors display. In my case I saw white page. This one fixes :) Thanks. – l00k Jul 12 '17 at 12:58
for initial white-page errors (pre-magento / PHP) this does provide better results. – Rock_Artist Aug 31 '17 at 09:50
This is already contained in `app/bootstrap.php` as a commented code line. One may also remove the comment there… – feeela Nov 21 '19 at 14:57
First, check your `php.ini`. If error_reporting or display is turned off there, you should fix it there instead of in the `bootstrap.php`. Otherwise you end up displaying errors in production and maybe leaking sensible data. – stollr Jul 23 '20 at 09:57

Enabling Error reporting in magento2 is little tricky , as magento2 now comes with 3 different modes

Default
Developer
Production

Magento2 by default install in “default” mode and thats why you dont get the error log at the front-end of the site , that can a viewed at magento error log . You may check the complete details over here http://devdocs.magento.com/guides/v2.0/config-guide/bootstrap/magento-modes.html

How to enable developer mode in Magento2

This is must have if you are a developer and building extension and template for magento2 , magento provide a command for this purpose . Login in to your linux terminal and under magento execute

php bin/magento deploy:mode:set developer

and it will enable the developer mode under your magento instance for production mode you can set the mode to production or default .

still if you are experiencing in error reporting

you can give a try by renaming local.xml.sample to local.xml under pub/errors

There is a place for this. In bootstrap.php, there is:

#ini_set('display_errors', 1);

Just uncomment that.

1) app/bootstrap.php, there is:

Kindly uncomment that.

2) Run below commands

php bin/magento cache:flush

`php bin/magento cache:clean` is a subset of `php bin/magento cache:flush`, in other workds you only need run the `cache:flush` – Barry Apr 17 '19 at 07:55

sometimes we should look at the issue a bit wider than it appears, this is also in the scope of the question. – shustr8 Feb 04 '20 at 12:22

Instead of editing index.php or app/bootstrap.php file, you can also edit the .htaccess file to enable PHP display errors settings.

Write the following lines of code at the end of the .htaccess file present in your Magento2 website's root directory:

## enable PHP's error display settings
php_value display_errors on
## set error display to E_ALL
php_value error_reporting -1

After that,

Open terminal
Go to your Magento's root directory
```
cd /path/to/your/magento/root/folder
```
Run the following command to enable developer mode:
```
php bin/magento deploy:mode:set developer
```
To check your current developer mode, you can run the command:
```
php bin/magento deploy:mode:show
```

Please Put the following code in index.php

   ini_set('error_reporting', E_ERROR);
   register_shutdown_function("fatal_handler");
   function fatal_handler() {
     $error = error_get_last();
     echo("<pre>");
     print_r($error);
   }
