How to Fix “Add New Plugin Button Missing” in WordPress (Complete 2025 Guide)

The “Add New Plugin” button missing in WordPress is one of those issues that instantly raises panic — especially when you urgently need to install a plugin for security, SEO, caching, or a client deadline.

You log into your WordPress dashboard, go to Plugins → Installed Plugins, and suddenly:

• There is no “Add New” button

• You can’t upload plugins

• You can’t search the plugin repository

• Everything feels locked down

This problem affects beginners and advanced users alike, and it’s more common than most people realize. The good news?
In almost every case, this issue is 100% fixable once you identify the root cause. While fixing the missing Add New Plugin button restores critical functionality, it’s also a good opportunity to review overall WordPress practices that impact your site’s performance and rankings. Plugins are essential tools for SEO, but improper setup or oversight can lead to avoidable errors. For a deeper dive into common pitfalls, check out this guide on the 10 on-page SEO mistakes WordPress users make, which helps ensure your site is optimized while maintaining full control over your plugins and dashboard.

In this in-depth guide, you’ll learn every possible reason why the “Add New Plugin” button disappears and step-by-step solutions to restore it safely — without breaking your site.

This guide covers:

• User roles and permissions

• WordPress Multisite limitations

• wp-config.php restrictions

• Hosting-level blocks

• File permission issues

• Security plugins

• Database and core settings

• Real-world fixes used by professionals

Let’s fix it properly — once and for all.

What Does the “Add New Plugin” Button Do?

The Add New Plugin button allows administrators to:

• Install plugins from the WordPress.org repository

• Upload premium plugins in ZIP format

• Extend WordPress functionality instantly

If this button is missing, your WordPress site becomes restricted, limiting updates, features, and scalability.

Who Can See the “Add New Plugin” Button?

By default:

• Only Administrators can see the “Add New” plugin button

• Editors, Authors, Contributors, and Subscribers cannot

So the first rule:

If you are not an Administrator, the button will not appear.

But that’s just the beginning.

1. You Are Not Logged in as an Administrator

Symptoms

• Plugins menu is visible

• “Add New” button is missing

• No upload option

How to Fix

1. Go to Users → All Users

2. Click your username

3. Check the Role

4. Set it to Administrator

5. Save changes

6. Refresh the dashboard

If you’re on a client site, request admin access — there’s no workaround for this. Sometimes the missing Add New Plugin button is part of a broader admin access problem rather than a standalone issue. Session conflicts, cookie mismatches, or corrupted login states can cause WordPress to partially load the dashboard while hiding key controls. If you’re experiencing repeated logins, sudden redirects, or restricted admin views, resolving the underlying authentication problem is essential. This guide on the common causes and fixes for a WordPress login redirect loop explains how to restore stable admin access without breaking your site.

2. WordPress Multisite Network Restrictions

If your site is part of a WordPress Multisite Network, plugin installation works differently.

What Happens in Multisite

• Only Super Admins can install plugins

• Regular site admins cannot add plugins

• The “Add New” button is hidden by design

How to Confirm Multisite

Check wp-config.php for:

How to Fix

1. Log in as Super Admin

2. Go to Network Admin → Plugins

3. Install plugins from there

4. Activate them per site if needed

If you’re not the Super Admin, you must request plugin installation access.

3. Plugin Installation Disabled in wp-config.php

Sometimes WordPress is explicitly configured to disable plugin and theme installation.

Common Code Causing the Issue

Check wp-config.php for:

or:

Why This Happens

• Added by developers for security

• Set by managed hosting providers

• Left behind after staging or hardening

How to Fix

Edit wp-config.php and either:

• Remove the line completely
  or

• Set it to false:

Save the file and refresh your dashboard.

4. Managed WordPress Hosting Restrictions

Some managed hosts intentionally disable plugin installations.

Common with:

• Enterprise hosting plans

• Locked-down staging environments

• Agency-controlled hosting

Signs This Is the Issue

• Admin access but no Add New button

• No error messages

• Everything else works fine

How to Fix

Contact your hosting provider and ask:

• If plugin installations are restricted

• If your plan allows custom plugins

• If you need elevated permissions

This is common on performance-optimized hosting environments.

5. File Permissions Are Incorrect

WordPress needs proper file permissions to install plugins.

Recommended Permissions

• Folders: 755

• Files: 644

• wp-content/plugins must be writable

How to Fix via FTP or File Manager

1. Connect using FTP or hosting File Manager

2. Navigate to /wp-content/

3. Right-click plugins folder

4. Set permissions to 755

5. Apply to subfolders if needed

If WordPress can’t write to this directory, the Add New button may disappear.

6. Security Plugin Is Blocking Plugin Installation

In many cases, aggressive security hardening is the root cause behind missing admin features. Brute-force protection, login lockdowns, and admin restriction rules can unintentionally block legitimate actions like plugin installation. If you’re tightening security after resolving this issue, make sure it’s done correctly. WPThrill’s guide on how to secure WordPress login against brute force attacks explains how to protect your site without breaking core admin functionality.

Security plugins are a very common cause of this issue.

Plugins like:

• Wordfence

• iThemes Security

• Sucuri

• All-in-one security plugins

What They Do

• Disable file modifications

• Restrict admin actions

• Hide UI elements

How to Fix

1. Temporarily disable your security plugin

2. Refresh the Plugins page

3. If the button reappears:

   • Re-enable the plugin

   • Adjust settings related to file changes or admin restrictions

Look for options like:

• “Disable file editing”

• “Prevent plugin installation”

• “Lock admin features”

Security plugins are essential, but not all are configured with the same balance between protection and usability. Some aggressively lock down file modifications, which can cause admin features like the Add New Plugin button to disappear. Choosing the right tool — and configuring it properly — makes a big difference. WPThrill’s comparison of the best WordPress security plugins helps you pick solutions that secure your site without unnecessarily restricting core WordPress functionality.

7. A Custom Plugin or Theme Is Removing the Button

When a theme or custom plugin silently removes admin features, WordPress may not display any visible error messages. Enabling debug mode can reveal hidden PHP notices or fatal errors that explain why parts of the dashboard aren’t loading correctly. WPThrill’s guide on how to enable WordPress debug mode to find errors shows how to safely diagnose issues without exposing sensitive information to visitors. Some custom code intentionally hides plugin installation.

How This Happens

• Client-specific plugins

• White-label admin dashboards

• Custom themes with admin restrictions

How to Test

Add this to wp-config.php temporarily:

Then:

• Switch to a default theme

• Disable all plugins via FTP

• Check if the button returns

If it does, re-enable plugins one by one to find the culprit.

8. Database-Level Capability Issues

Sometimes the missing Add New Plugin button is a symptom of deeper database corruption. Corrupted tables, broken capabilities, or incomplete updates can prevent WordPress from recognizing administrator privileges or loading plugin interfaces correctly. Before taking drastic steps like reinstalling core files, it’s wise to inspect and repair your database. This guide on WordPress database corruption causes, prevention, and fixes provides detailed steps to restore your database and ensure full admin functionality.

User capabilities can become corrupted in the database.

Symptoms

• Admin role exists

• Still no Add New button

• Other admin features missing

How to Fix

Install (or manually add) a role editor plugin once access is restored, or reset capabilities using phpMyAdmin:

Check wp_usermeta table for:

• wp_capabilities

• wp_user_level

Ensure your user has:

This fix should be done carefully or by professionals.

9. WordPress Core Files Are Corrupted

Before making changes to core files, wp-config.php, or file permissions, it’s critical to have a reliable backup in place. Many WordPress issues — including missing admin features like the Add New Plugin button — can escalate quickly if a mistake is made. Using one of the trusted solutions listed in WPThrill’s guide on the top backup plugins for WordPress ensures you can restore your site instantly if something goes wrong.

Rare, but possible after:

• Failed updates

• Malware cleanup

• Manual file changes

In more serious cases, malware infections or incomplete cleanup attempts can disable core WordPress capabilities, including plugin installation. Malicious code often modifies permissions, user roles, or file modification constants without leaving obvious signs. If you suspect your site was previously compromised, following a step-by-step approach to manually remove malware from WordPress can help restore normal admin functionality and prevent the issue from recurring.

Fix

1. Download a fresh copy of WordPress

2. Replace:

   • /wp-admin

   • /wp-includes

3. Do NOT overwrite wp-content or wp-config.php

This restores missing core functionality safely.

In some cases, the missing Add New Plugin button is not caused by permissions alone but by server-level limitations that prevent WordPress from loading admin components correctly. PHP memory exhaustion can silently break parts of the dashboard without showing visible errors. If you notice other admin issues alongside this problem, increasing your memory limit may be necessary. WPThrill’s guide on how to fix the Allowed Memory Size Exhausted error in WordPress walks through safe ways to resolve memory issues without destabilizing your site.

10. Temporary Workaround: Manual Plugin Installation

If you urgently need a plugin:

1. Download the plugin ZIP

2. Extract it

3. Upload the folder to:

   /wp-content/plugins/


4. Go to Plugins → Installed Plugins

5. Activate it

This does not fix the root issue — but it keeps you moving.

Why This Issue Hurts SEO, Security, and Growth

Without plugin installation:

• You can’t install SEO plugins

• You can’t add security protection

• You can’t optimize performance

• You lose flexibility and control

Fixing this is not optional for a serious WordPress site.

Final Checklist to Restore the “Add New Plugin” Button

• Confirm Administrator role

• Check Multisite restrictions

• Review wp-config.php

• Verify hosting limitations

• Fix file permissions

• Disable security plugins temporarily

• Scan for custom admin restrictions

• Repair core files if needed

Once these are checked, the button will return.
