Summary:Caching plugins like WP Rocket can prevent the widget from displaying because JavaScript files from the Trustindex CDN may be blocked, combined, or minimized incorrectly.
Disable JS combining/minifying on the page where the widget is embedded.
In your cache plugin:
Go to Excluded JavaScript Files
Save changes and clear the cache.
Trustindex widgets use JavaScript loaded from a CDN.
Excluding the file ensures your caching plugin does not interfere with the latest features or fixes.
The CDN file is optimized, so it does not slow down your site for visitors.
