[Plugin: WP SlimStat] Dashboard Widgets not working on Multisite

I have the same problem too. In a Multisite environment, also in a subdomain and a sub directory structure. It is the same.

No dashboard are visible, i activated the plugin in the multiste and on every site i have.

The same error, no Dashboards are visible. No Errors in the Apache Log.

Please advise.

On second thought, a much better option than modifying the plugin code would be to use a filter on the get_option('active_plugins') to add the SlimStat plugin when it is active for multisite, so just add this to your functions.php:

function activate_slimstat_dashboard_multisite($plugins){
	// only run on multisite admin index screens ($pagenow isn't available, may need to mod if you are using subdirectories)
	if (is_multisite() && $_SERVER['SCRIPT_NAME'] == "/wp-admin/index.php"){
		$slimstat_plugin = 'wp-slimstat/wp-slimstat.php';
		// check if plugin is active network wide and if so add to site plugins
		if (array_key_exists($slimstat_plugin, get_site_option('active_sitewide_plugins', array())))
			$plugins[] = $slimstat_plugin;
	}
	return $plugins;
}
add_filter( 'option_active_plugins', 'activate_slimstat_dashboard_multisite' );

EDIT: in the interest of not updating this post repeatedly, the latest working code is here – http://justin.ag/technology/activate-wp-slimstat-dashboard-widgets-in-wordpress-multisite/

You would add this in your /wp-content/themes/YOUR_THEME/functions.php. The widgets won’t show up on your network dash board (/wp-admin/network/) since it wouldn’t know what site to pull the stats for, but it will show up on the dashboards for your specific sites. I am using the code that I posted to my site (which should work for multisites using subfolders & subdomains) and it’s working for me.

Ahh, i think I know why – the plugins files are loading before functions.php, and the call in the slimstats plugin doesn’t use an action/filter hook so it executes immediately (which is why $pagenow isn’t available). With the filter being added in your theme, the call from the plugin happens before the filter is exists, so it doesn’t modify the results of get_option().

The reason it works for me is that I actually wrote a plugin to use instead of the functions.php file for code that I want to keep around even if I change themes, and it is set up to run before any of the other plugins.

If you want to do the same and use a filter instead of modifying the plugin, which I would recommend, you can set up your own custom functions.php plugin based on this code: http://justin.ag/technology/wordpress-plugins/wordpress-plugin-custom-functions-php/.

Basically just create a custom-functions-php folder in your plugins directory, add the code from that link to a file called custom-functions.php and then include the filter from http://justin.ag/technology/activate-wp-slimstat-dashboard-widgets-in-wordpress-multisite/ in a file called functions.php in the custom-functions-php folder. Activate the new Custom functions.php plugin in your admin and you should be good to go – it should work as a site or network-wide plugin depending on how you want to distribute the custom functions. Nifty for other code too.
