Correct permissions are vital for both security and functionality.
- Directories/Folders: Should be set to 755. This allows the owner to read/write/execute while others can only read and execute.
- Files: Should be set to 644. This allows the owner to read/write, while others can only read the file.
- Critical Files: Files like
wp-config.phpshould have stricter permissions (e.g., 400 or 440) to prevent unauthorized access .
