In large WooCommerce stores with many products and many categories, the admin panel slows down sometimes when no Database caching tools are installed.
To solve this issue you need to replace a php file in the redux framework plugin. Follow these steps:
- Download the following file: https://github.com/db-dzine/redux-framework/blob/master/ReduxCore/framework.php
- Open up the Redux Framework plugin folder via FTP: wp-content/redux-framework/ReduxCore/
- Replace the framework.php file on your server with the one you have just downloaded
The patched file adds some transients to the WP Queries and decreases the load time.
