If you have ever developed a plugin for WordPress you may encounter an unhelpful messages saying your plugin generated N characters of unexpected output during plugin activation.

A nest solution offered by The Hungry Coder is to capture the hidden output into an option or a text file, then view the error message at your leisure.

To save the errors enter the following in functions.php:

add_action('activated_plugin','save_error');
function save_error() {
update_option('plugin_error',  ob_get_contents());
}

Then, reactivate your plugin and find the error in the wordpress option table.

echo get_option( 'plugin_error' );
