The JSON Cache feature in the store locator plugin offers improved performance by preserving JSON data and serving them instead of making repeated server requests.

Key Points:

• Preserves JSON data in advance, eliminating the need for frequent requests to admin-ajax.php and database queries.
• Supports serving JSON files for each active language, ensuring accurate and localized results on multilingual websites.
• Enhances loading speed by retrieving data from pre-saved JSON files, resulting in a faster and more responsive store locator experience.
• Reduces server load for high-traffic sites by avoiding repeated server calls and database hits.
• Provides the ability to restrict access to the wp-admin.php section, as the JSON files are saved in the wp-uploads directory.

When JSON cache is disabled, please refer to the guide article if your stores are still not visible, in order to resolve the issue.
