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 Name : wp-config.mlm-backup-2026-09-02-183045.php (timestamped using your site’s configured time zone) Location : Same directory as your wp-config.php file Number of Backups : Keeps only the most recent backup, replacing the previous one Automatic Restore : If any error occurs during update, your original wp-config.php is automatically restored Manual Restore : You can manually restore the backup file via FTP/cPanel if needed This means you can update memory limits with confidence, knowing your configuration is always protected.
