Hi there!
Translation of your message for anyone who pops onto this thread later:
My shopping cart is generating a value without the person buying it and when I click on the cart it is empty but a value of 86.25 appears without anyone having bought it, I tested it in several other places and is having the same problem… how do I solve it ?
This kind of problem is usually caused by a conflict with your theme or with another plugin.
The best way to determine this is to:
<ul>
<li>Temporarily switch your theme to <a href="https://www.woocommerce.com/storefront/" target="_blank">Storefront</a></li>
<li>Disable all plugins except for WooCommerce</li>
<li>Repeat the action that is causing the problem</li>
</ul>
This is best done on a staging site. That's a copy of your live site, so you can test things out without making changes to your actual site. Some hosting companies offer a staging site service within their hosting plans. If yours does not, there is a great free plugin that will allow you to build a complete staging site with a few button clicks: https://wordpress.org/plugins/wp-staging.
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. <a href="https://docs.woocommerce.com/document/how-to-test-for-conflicts/">You can find a more detailed explanation on how to do a conflict test here.</a>
Not having my woocommerce plugin. Can you explain the problem a little?
