Hi @supplementplace,
This error is usually caused by a JavaScript conflict, a plugin/theme conflict, or corrupted WooCommerce Analytics data.
As a first step, could you please try the following after a full site backup?
- Clear all caches, including your browser cache, site cache (WP Rocket, LiteSpeed Cache, etc.), and CDN cache if applicable.
- Temporarily switch to a default theme such as Storefront or Twenty Twenty-Four and check whether Analytics loads correctly.
- Disable other plugins one by one, especially analytics, optimization, or security plugins, to identify any conflicts. It may be helpful to start with recently installed or updated plugins.
Could you also let us know:
- Which versions of WordPress and WooCommerce are you currently using?
- Are there any additional errors shown in the browser’s Developer Console?
- Have there been any recent updates or changes on the site before the issue started?
These details should help us narrow down the cause of the issue.
SOLVED – the issue was the WordPress block editor failing to load a core JavaScript file called undo-manager.min.js. Without that file the editor cannot start.
- Connected to the site over SSH and confirmed the asset files on the server are healthy.
- Reproduced the 404 from the CDN and proved it was a cache poisoning issue, not a code or database fault.
- Purged the cache directly inside Cloudflare for the affected paths.
- Purged all caches inside Kinsta, including the site cache, object cache, and Kinsta’s edge CDN.
- Bumped the asset version hashes so any stale references are forced to refetch a clean copy.
