Could you please check how it works with some default WordPress themes like TwentyTwenty or WooCommerce Storefront to understand is it our theme issue or not?
My site and promotions are live. Approx, $500 is the daily sale. How can I put the site down and check by changing the theme? This would be a direct cash loss. Please suggest an alternative.
In this case, you need to create a staging development copy of your website. There, you will be able to do such kind of experiments without any harm to your production website.
We don’t see any errors related to our theme in your logs so you need to check how it works with other themes first.
