Description

Memory Limit Manager makes it incredibly easy to configure your memory limits without manually editing wp-config.php. With a beautiful, user-friendly interface and powerful features, you can increase memory limits with a single click.

Key Features

  • One-Click Updates – Change memory limits with a single button click
  • Quick Presets – Common configurations (128M/256M, 256M/512M, 512M/1G, 1G/2G)
  • Automatic Backups – Creates timestamped backups before any changes
  • Conflict Detection – Identifies if memory limits are defined elsewhere
  • System Diagnostics – File permissions and writability checks
  • Manual Fallback – Copy-paste code if automatic updates don’t work
  • Opcode Cache Clearing – Immediate effect after changes
  • Beautiful UI – Modern, card-based layout with real-time validation

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

Security

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

Documentation

Full documentation is available in the plugin’s README.md file and at the plugin website.
