This document explains how caching works in Product Designer App (PDA) and how to clear cache when needed.

Cache Overview #

PDA uses caching to reduce database load and improve plugin performance. Cached data helps the plugin run faster and more efficiently. In some cases, you may need to remove cache, for example:

• When newly loaded data is not displayed correctly
• When you want to clean unused cache data to free up storage space

Cache Creation #

Cache is automatically created when customers use the PDA plugin. No manual action is required. Please make sure the cache folder has writable permission:

Root/wp-content/plugins/product-designer-app/cache

If this folder is not writable, the plugin may not be able to store cache data correctly.

Clear Cache #

You can clear all cache data or remove cache for specific parts of the plugin.

Steps:

1. Go to WordPress Admin Panel
2. Navigate to Product Designer App → Settings
3. Open the Advanced tab
4. Click Remove Cache

After clearing the cache, new cache files will be regenerated automatically when the plugin is used.

Notes #

• Clearing cache does not remove designs or configuration data.
• It is safe to clear cache at any time.
• Cache files will be recreated automatically after removal.
