(NOTE: Before saying this plugin is broken, please understand what this plugin does. It’s meant for WordPress installs that have multiple NETWORKS.)
Adds the ability to have different themes available to different NETWORKS in a multisite atmoshpere.
WordPress allows for multiple “networks”, these are not to be confused with sites. A network holds blogs underneath of it.
This plugin will allow you to separate themes into different directories so they’re only accessable and viewable to the networks you choose.
The plugin will attempt to create a directory in the /wp-content/ directory named /ms-themes/. If it fails to create it, then you will need to make one.
In the /ms-themes/ directory you will create a folder for each network that you want to allow only certain themes to.
Example: 
If you have a theme named “Snarfer Theme”, and you want to only allow it to be viewable/available to the network (and all sites on that network) with the site_id of 7, you would place the snarfer theme directory in /wp-content/ms-themes/7/
Future releases:
<ul>
<li>Network option to turn off auto creation on/off network directories, index.php files.</li>
<li>Network option to display network ID in the footer of sites so network admins can easily tell what network a site is under.</li>
</ul>

InfiniteWP Client

We have 100 sites that we manage, update, review and monitor on a daily, weekly and monthly basis for customers.  Infinitewp makes this so simple to manage.  You can instantly see needed updates, You can setup staging sites to manage updates before updating live sites which is essential for our highly custom ecommerce sites.  

Support is top notch.  We have had 2 issues.  One was a 2 second fix where we simply did not RTFM and missed the step.  The other issue was recent and had to do with the recent update in WP All in One Security in which a specific setting was blocking access.  The support team could have taken the easy way and said - this setting is blocking our access, you have to leave it unchecked and not use it, but the infinitewp team did things the right way and updated their plugins to work around the security setting.  

This plugin is well worth the price.  It saves us hours every week and we highly recommend. 

BEST tool for any wordpress dev who manages sites

I have been using InfiniteWP for years, and highly recommend. It provides a quick way to see what sites have updates, and a way to target updating only specific sites/plugins/core. I've tried others, like ManageWP, but they lack features I need, like being able to only update specific plugins, or get a list of all sites I just updated so I can log into each, and check the updates didn't break anything. Most of my clients' sites use WP Engine's Smart Plugin Manager, and I use InfiniteWP so I can ensure the automatic updates keep running (they've stopped on quite a few of my sites, and InfiniteWP is how I track when this happens so I can get the automatic updates running again). I have InfiniteWP set up to send me an email of all sites that have updates daily. Asvin has provided fast, awesome support anytime I've had an issue over the years - which has only happened a couple of times when dealing with more advanced settings.

A must-have to manage site updates

Install this plugin on unlimited sites and manage them all from a central dashboard. This plugin communicates with your InfiniteWP Admin Panel.
