How to Fix Incorrect File Permissions Causing Plugin Activation Issues

Solution verified by Salah Uddin

Quick Tips:

Incorrect file and folder permissions can prevent plugins from activating. Set folders to 755, files to 644, and ensure the web server user owns them. WPFix247 can configure this for you safely.

Why File Permissions Affect Plugin Activation

If your WordPress plugins can’t be activated or updated, incorrect file or folder permissions are often the cause. WordPress needs permission to read and write plugin files during installation and activation.

1. Correct Folder and File Permissions

Using FTP or your hosting File Manager, set permissions as follows:

Folders: 755
Files: 644

This ensures that the web server can write files but keeps them secure.

2. Check Ownership of Files

On VPS or dedicated servers, ensure your web server user (e.g., www-data or apache) owns the WordPress files. Use SSH if available:

chown -R www-data:www-data /path/to/wordpress

3. Adjust Permissions Recursively

If you need to fix all permissions quickly, run:

find /path/to/wordpress/ -type d -exec chmod 755 {} ;
find /path/to/wordpress/ -type f -exec chmod 644 {} ;

4. Check Security Plugins or Hosting Restrictions

Some security plugins or hosts may override permissions. Disable such plugins temporarily and confirm with your hosting provider if the issue persists.
