All Modula Pro extensions are built into the Modula PRO plugin, so there is nothing to download or install. Once your license is active, you turn on the extensions you want in Modula → Extensions.
Before you start
Modula and Modula PRO must be installed and active. Your license key must be activated too. See Install the Modula WordPress plugin and activate the Pro version and how to activate your license.
Switch Modula Pro extensions on or off
- Go to Modula → Extensions. The license card at the top shows your license, its status, how many sites use it and your AI credits.
-
Find the extension under All extensions. The extensions are grouped by plan: Starter, Trio and Business. Each plan includes the extensions of the plans before it.

- Click the switch in the Status column to turn an extension on or off. The change happens right away, and there is no Save button.
You can also change a whole group at once. Activate all or Deactivate all next to a plan’s name switches the whole group.
Extensions with their own options have a Settings link under their name. To filter the list, use All, Active and Inactive above it.
Good to know
- Extensions that aren’t in your plan can’t be switched on. The page offers a link to upgrade to the plan that has them (how to upgrade).
- If you deactivate the license on the license card, all extensions turn off until you activate a key again.
- Switching off Password Protect asks you first, because it removes the password from your protected galleries and albums.
If an extension won’t switch on
First check the basics. In Plugins, both Modula and Modula – PRO must be active. The license card in Modula → Extensions must show your license as Active.
You may have switched Modula off and on again, for example while looking for a plugin conflict. Modula PRO stays off after that, so click Activate under Modula – PRO.
Old add-on plugins are still installed
Before the extensions were built into Modula PRO, each one was a separate plugin. Examples are Modula – Download, Modula – Image Guardian, Modula – Pagination, Modula Video and Modula Advanced Shortcodes.
These old plugins can’t be activated any more. In Plugins, their Activate link is gone and WordPress shows:
You cannot activate this plugin as it has unmet requirements.This plugin cannot be activated because required plugins are missing or inactive.Modula PRO 3.0 switches them off. Under each one it shows this message: “This add-on has been superseded by the Pro plugin and is no longer needed. You can safely delete it.”
To clean up, follow these steps:
- Update Modula and Modula PRO to the latest versions.
- In Plugins, delete the old add-on plugins.
- In Modula → Extensions, switch on the extensions you need.
There’s nothing to download separately. The old add-on downloads in your account give a permission error.
You upgraded your plan, but its extensions are still locked
After an upgrade, your site keeps using the old plan for up to an hour. Clearing your site’s cache, the saved copy of your pages, doesn’t change that. To load the new plan now:
- Go to Modula → Extensions.
- On the license card, click Change key.
- Paste the same key and click Activate.
- Switch on the extensions of your new plan, for example Standalone.
If they’re still locked, click Deactivate on the license card and confirm with Deactivate license. Then paste your key under Enter your license key and click Activate.
Deactivating turns all extensions off, so switch the ones you use back on afterwards.
