 * Hi,
 * I’m currently updating the plugins on a website and noticed that when I click
   on details for “Addons Manager and Support” as well as “WP Users Addon” (both
   are plugins from The Newsletter Team), I receive a message that says “plugin 
   not found”.

 * These are the only two plugins where I find this behavior. Everything else, including
   the original “Newsletter plugin” show the details as expected.
 * What’s the reason for this? And is there a workaround?

 * The detail link does not work since they’re not stored on WP.org, they’re served
   by the Newsletter plugin server.

 * Hey [@satollo](https://wordpress.org/support/users/satollo/)
 * Should I download both plugin zip files from The Newsletter website (it seems
   to require a free signup) and upload to the server? I’ve done manual updates,
   it’s not an issue.
 * Or is there a way to update directly? I checked under Newsletter > Addons Manager
   and didn’t see anything related to updating.

 * Hi, if you the “update now” they should update, anyway I need to ask you to move
   the discussion to our forum on the Newsletter plugin site, since those are addons
   not available from wordpress.org, we provide support on that specific site while
   this forum is reserved to the main plugin. Thank you for your collaboration.

 * [@satollo](https://wordpress.org/support/users/satollo/) In any case also for
   the free plugin you can change the detail link to the Plugin URI from plugin 
   header with a snippet like this in your plugins:
 *     ```wp-block-code
       add_filter( 'admin_url', function( $url ) {	if ( strpos( $url, 'plugin-install.php?tab=plugin-information&plugin=' . dirname( plugin_basename( __FILE__ ) ) ) !== false ) {		$plugin_data = get_plugin_data( __FILE__ );		if ( !empty( $plugin_data['PluginURI'] ) ) {			$url = str_replace( admin_url( 'plugin-install.php' ), $plugin_data['PluginURI'], $url );		}	}	return $url;});
       ```
