Disable Errors in Plugins is a WordPress plugin that simply disables error reporting and error logging for all plugins.
This plugin should be used mostly with development purposes. It does NOT encourage badly written code with errors, warnings or notices. Its main goal is to help plugin & theme developers in situations when they have to use plugins that have notices or warnings. This helps to isolate any external errors, allowing developers to focus on improving their own code and making it errorless.
The plugin file name begins with <code>000-</code>, because this way it would assure being loaded before 99.9% of the plugins.

Helps ignore 3rd party notices
