Hi Jeff

Sorry for the late reply. I have narrowed it down to a conflict with the Yith Themes Pre-order plugin. The error I get in the admin panel is:
Uncaught TypeError: Cannot read properties of null (reading ‘join’)
in the wp-content/plugins/woocommerce-wholesale-prices/js/backend/wwp-percentage-wholesale-pricing-on-product-level.js?ver=2.1.4 file.
I am not sure if that would be of help?

There is definitely an issue on variable products. I have disable your plugin, to even edit the pricing on a variable product.
