Easily manage memory limits through a beautiful admin interface with advanced conflict detection.

== 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 wp-config.php Backups** - Creates timestamped backups of your wp-config.php file before any changes (format: wp-config.php.backup-YYYY-MM-DD-HHMMSS). Keeps 5 most recent backups and auto-restores on failure
* **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

= 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

== Frequently Asked Questions ==

= Is this plugin free? =

Yes! Memory Limit Manager is 100% free and open source.

= Will this work with my hosting? =

Yes, as long as your wp-config.php file is writable. Most hosting providers allow this.

= Can I undo changes? =

Absolutely! The plugin automatically backs up your **wp-config.php file** (not your entire site) before making any changes. 

Backup files are named like: wp-config.php.backup-2026-01-15-223045

You can find them in the same directory as your wp-config.php file. The plugin keeps the 5 most recent backups. To restore manually, simply rename a backup file back to wp-config.php via FTP or cPanel File Manager.

= What if automatic updates don't work? =

No problem! The plugin provides a manual configuration option with copy-paste code that you can add to wp-config.php via FTP or cPanel.

= What exactly gets backed up? =

Only your **wp-config.php file** is backed up - NOT your entire site, database, or other files. This is a safety measure specific to the configuration file that gets modified. The backup happens automatically every time you update memory limits.

= Is it safe to use? =

Absolutely! The plugin follows WordPress security best practices, creates automatic wp-config.php backups, and validates all input before making changes. If anything goes wrong during an update, your original wp-config.php is automatically restored.

= Does it work with multisite? =

Yes, the plugin is multisite compatible.

= Will it conflict with other plugins? =

No, the plugin includes conflict detection and will warn you if memory limits are defined elsewhere (themes, mu-plugins, or other plugins).

= What values should I use? =

Use the Quick Presets as a starting point:
* Small sites (blogs): 128M / 256M
* Standard sites: 256M / 512M
* Large sites (e-commerce): 512M / 1G
* Enterprise sites: 1G / 2G
