Plugins can be ‘Network Activated’ or ‘Network Deactivated’ via the Plugins page on the Network Admin dashboard.

When a plugin is network activated that plugin is automatically activated network wide and is available for use on all sites across the network.

If a plugin is ‘network activated’ it no longer appears in the Site Admin dashboard at all.  Only a Super Admin user is able to deactivate a “network activated’ plugin via the Plugins page in the Network admin dashboard.

Plugins are network enabled as follows:

1. Click on the Network Admin link in the drop down menu under your username.

2. Click on Plugins on the Network Admin dashboard.

3.  Select the plugins you want to make available to all sites by either:

• Clicking on Network Activate below the plugin name
• Or selecting all the plugins you want to enable, then select Activate from the Bulk Actions drop down menu and click Apply
