Why Use This Plugin?

Manually editing wp-config.php can be:
– Intimidating for non-technical users
– Error-prone (syntax errors can break your site)
– Difficult to verify if changes took effect

Memory Limit Manager solves all these problems with a safe, user-friendly interface that handles everything automatically.

What It Does

This plugin allows you to configure two WordPress memory limit constants:
1. WP_MEMORY_LIMIT – Controls memory available on the frontend (default: 40M)
2. WP_MAX_MEMORY_LIMIT – Controls memory available in admin area (default: 256M)

Increasing these values can help resolve:
– “Memory exhausted” errors
– Plugin/theme activation failures
– Image upload problems
– Slow admin performance

Automatic Backup System

For your safety, the plugin automatically backs up your wp-config.php file before making any changes:

• Backup File Format: wp-config.php.backup-2026-01-15-223045 (timestamped)
• Location: Same directory as your wp-config.php file
• Number of Backups: Keeps the 5 most recent backups, auto-deletes older ones
• Automatic Restore: If any error occurs during update, your original wp-config.php is automatically restored
• Manual Restore: You can manually restore any backup file via FTP/cPanel if needed

This means you can update memory limits with confidence, knowing your configuration is always protected.

Security

• Nonce verification for CSRF protection
• Capability checks (administrator-only access)
• Input sanitization and validation
• Secure file operations with error recovery
