Recently I have had an issue that shop / woocomerce is not functioning.
Upon adding to the cart button click there is round circle and unable to place an order.
4 or 5 days before orders were received.
I have updated woocomerce & all plugins. But issue remians.
I hope you can guide what is wrong and resolve the issue.
There is an issue with the 3rd party plugins. Please deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Otherwise, if the issue still exists then keep the 3rd party plugins deactivated and so I will check and give you a possible solution.
