“File not found.” Error After Activating Plugin

Hello there,

I just installed the plugin on a test site. After installing the plugin I clicked the “Activate” button.

This lead me to a File not found. error. ??

I looked into your source code.

public function impact_activate( $plugin ) {
	$arr = explode( '/', $plugin );
	if ( count( $arr ) >= 1 && strpos( $arr[ count( $arr ) - 1 ], 'impact' ) !== false ) {
		$store_url = home_url();
		$path      = '/wp-admin/admin.php?page=impact-settings';
		$url       = $store_url . $path;
		wp_safe_redirect( $url );
		exit;
		{...}
	}
}

It looks like you’re using home_url() which is generally used on the front-end of the website.

If WordPress is installed in a subdirectory such as example.com/wp/ then when you activate the plugin it will load example.com/wp-admin/admin.php?page=impact-settings which doesn’t exist.

I recommend using admin_url() instead.
