Fatal Plugin Auto Deactivator – Never let a plugin break your site

Automatically deactivates plugins that cause fatal errors to prevent site crashes and keep your WordPress site running smoothly.

Juliette Reinders Folmer

Ever been “greeted” when you activated a plugin with the dreaded:
<blockquote>
This plugin generated # characters of unexpected output during activation….
</blockquote>
And wondered what the unexpected output was ?
Or wondered whether a de-activation or uninstall routine was free of typical PHP errors ?
Well, no need to wonder anymore, as you can now see the output within your favorite debugging tool – the <a href="https://wordpress.org/plugins/debug-bar/" rel="ugc">Debug Bar</a>.
Debug Bar Plugin Activation adds a new panel to the Debug Bar which displays the output generated during plugin activation, deactivation and uninstall.
Once you’ve fixed the issues, you can remove the logged output straight from the Debug Bar panel. 
And when you uninstall a plugin, the associated logged activation and deactivation output entries will be removed automatically.

Debug Bar Plugin Activation

I know this plugin currently doesn't show any updates for several versions of WordPress.  However, it continues to work just fine.  I find it a necessary tool for plugin development.

It adds to the debug bar, and if there are any errors that occur during plugin activation, you can get them in the debug bar - an essential message if you're trying to develop a plugin and need to debug the activation process.

The plugin is an add-on to the Debug Bar plugin, so if you don't have that installed, it won't work.

Excellent tool for plugin developers


Just a note of thank you to the developer. And, a note to potential users, this still worked on my localhost dev site in helping me debug the activation error 'headers already sent'. The plugin allowed me to read the additional output to see where the error was coming from and resolve it. Thanks!
