In WordPress Multisite, the Plugins screen you see depends on your role, network settings, and how each plugin is activated. A complete inventory is normally available only at My Sites → Network Admin → Plugins to a Super Admin. Site Administrators may have no Plugins menu, may see only plugins enabled for their site, and will not see must-use plugins in the normal list.
Where the complete plugin list is managed
Multisite installs and manages plugins from the network dashboard rather than from each individual site dashboard. Sign in with a Super Admin account, open My Sites → Network Admin → Plugins, and inspect the network-wide inventory there.
The Network Admin link and network plugin controls are reserved for Super Admins. A site Administrator can administer content and settings for an individual site but does not automatically receive network plugin administration capabilities such as manage_network_plugins.

Why your site dashboard may have no Plugins menu
The site-level Plugins menu is disabled by default in Multisite. A Super Admin can make it available by going to Network Admin → Settings → Network Settings → Menu Settings and enabling the Plugins option, then saving the network settings.
#1 Best Overall
Enabling that menu does not turn a site Administrator into a network plugin manager. Role capabilities, custom capability filters, hosting controls, and the network’s configuration can still limit what the user can do or see.
Network activation is different from site activation
A plugin can be installed once for the network and then activated in two different ways:
Rank #2
| Activation state | What it means | What a site Administrator sees |
|---|---|---|
| Network Active | The plugin runs across the network’s sites. | The individual site view identifies it as Network Active; the site Administrator cannot deactivate it for just that site. |
| Active on one site | The plugin is enabled for a particular site without network-wide activation. | If the site’s Plugins menu is enabled and the user’s role permits access, the plugin can appear in that site’s list and may have site-level controls. |
| Installed but inactive | The plugin files are present but not currently enabled. | It may be visible to an authorized user in the relevant plugin list, but installation and updates remain network-admin responsibilities by default. |
When a plugin is network-activated, do not look for a per-site deactivation button. The network activation state is controlled from Network Admin.
Must-use plugins are intentionally missing
Must-use (MU) plugins are loaded from wp-content/mu-plugins. WordPress loads these files automatically when they exist; they are not activated or deactivated through the ordinary Plugins screen. Consequently, they do not appear in the default per-site plugin list.
To check for one, an administrator with server or hosting access must inspect the network’s wp-content/mu-plugins directory and its deployment process. A hosting platform, security service, or custom development workflow may place code there even when it is absent from the dashboard.
Use this troubleshooting sequence
- Confirm the account role. Check whether you are a Super Admin or only an Administrator for one site. Only the former has the normal network plugin-management access.
- Open the network inventory. As a Super Admin, use My Sites → Network Admin → Plugins rather than the individual site’s dashboard.
- Check the menu setting. If site Administrators need a Plugins menu, go to Network Admin → Settings → Network Settings → Menu Settings and enable Plugins.
- Read the activation label. A Network Active label means the plugin is controlled centrally and cannot be switched off for one site by its Administrator.
- Inspect must-use locations. Review
wp-content/mu-pluginswhen code is running but absent from the regular plugin list. - Account for local customization. Custom roles, capability filters, managed hosting policies, and WordPress-version differences can change labels or access. Compare the result with the network’s documented configuration.
How to see which plugins are active on which sites
The standard Network Admin Plugins screen is the authoritative place to manage the installed inventory, but it may not provide the cross-site matrix an operations team wants. A Multisite-specific tool such as Multisite Matrix advertises a network-only screen that shows plugin activation across sites.
Rank #4
Treat that listing as a feature description, not a compatibility or maintenance guarantee. Before installing any such tool, verify its support for your WordPress version, network size, PHP version, security policy, and current maintenance status. A visibility plugin should supplement—not replace—the network dashboard and server-level checks.
Choose the right view for the job
| Need | Best place or method | Access and caveat |
|---|---|---|
| See every installed plugin | Network Admin → Plugins | Normally requires Super Admin access. |
| Let a site Administrator view site plugins | Enable Plugins under Network Settings → Menu Settings | The menu is disabled by default; capabilities still apply. |
| Determine whether a plugin runs everywhere | Check for the Network Active state | Network activation removes site-level deactivation control. |
| Find code absent from the normal list | Inspect wp-content/mu-plugins and deployment records |
MU plugins are automatically loaded and omitted from the standard list. |
| Report activation by site | Evaluate a Multisite activation-matrix plugin | Confirm compatibility and maintenance before adoption. |
What “missing” usually means
A missing plugin is usually not deleted. It is more often outside the current user’s scope, hidden because the site Plugins menu is disabled, marked Network Active and therefore centrally controlled, or installed as a must-use plugin. Start with the account role and Network Admin inventory before changing files or reinstalling anything.
Frequently Asked Questions
Can a WordPress Multisite site Administrator install a plugin?
Not by default. Plugin installation, updates, deletion, and network activation are generally Super Admin responsibilities; custom capabilities or hosting policies can further restrict access.
Why does a network-activated plugin not have a deactivate link on my site?
Network activation applies the plugin across the network, so only a Super Admin can change that state from Network Admin.
Where can I find a plugin that is running but not listed?
Check the network’s wp-content/mu-plugins directory and deployment records. Must-use plugins load automatically and are omitted from the ordinary Plugins page.
