User Access Blocker is a simple yet powerful WordPress plugin that allows administrators to temporarily or permanently block user access without deleting their accounts. This is perfect for situations where you need to:
- Suspend user access during investigations
- Temporarily disable accounts for non-payment
- Block problematic users while preserving their content
- Manage user access during maintenance or transitions
Key Features
- Easy Toggle: Simple „Block Access” / „Unblock Access” button on user profiles
- Instant Effect: Blocked users are immediately prevented from logging in
- AJAX Powered: Block/unblock users without page refresh
- Secure: Multiple permission checks and nonce verification
- Non-Destructive: User accounts, posts, and data remain intact
- Admin Only: Only administrators can block/unblock users
- Self-Protection: Administrators cannot block themselves
- Activity Logging: All block/unblock actions are logged for security audits
- Clean Uninstall: Removes all plugin data when deleted
How It Works
- Navigate to any user’s profile page in WordPress admin
- Scroll to the „Access Control” section
- Click „Block Access” to prevent the user from logging in
- Click „Unblock Access” to restore their access
Blocked users will see: „Your account has been blocked. Please contact the administrator.”
Security Features
- Administrator-only functionality
- Nonce verification on all actions
- Permission checks at multiple levels
- Data sanitization and validation
- Secure AJAX implementation
- XSS protection through proper escaping
- Activity logging for audit trails

GYIK
-
Can blocked users still see their content?
-
No, blocked users cannot log in at all. They will be stopped at the login screen with an error message.
-
What happens to a blocked user’s posts and comments?
-
Nothing – all content remains intact. The plugin only prevents login; it doesn’t affect any user-generated content.
-
Can I block other administrators?
-
By default, the plugin prevents blocking administrator accounts for security reasons. This can be modified in the code if needed.
-
Can users unblock themselves?
-
No, only administrators can block or unblock users, and administrators cannot block themselves.
-
Is there a bulk block feature?
-
Not currently. Users must be blocked/unblocked individually from their profile pages.
-
Does this work with custom login pages?
-
Yes, the plugin hooks into WordPress’s authentication system, so it works with any properly coded custom login page.
-
What happens if I deactivate the plugin?
-
Blocked users will be able to log in again. The block status is only enforced while the plugin is active.
-
Will this plugin slow down my site?
-
No, the plugin is lightweight and only runs during login attempts and on user profile pages in the admin area.
