I have a problem with a plugin called no cart https://www.enriquejros.com/plugins/plugin-directo-checkout-sin-carrito/ I deactivated it and then deleted it but it still works. I also cleared the cache and uninstalled all plugins except woocommerce and it still works.
I can't find a way to make it stop working.
Here I leave the file structure of the plugin that I bought and if you need me to upload the code of any file, let me know.
Solution: The plugin was already solved when removing it, it did not delete the changes it made when it was activated and I had to manually delete some options that I activated
The option to redirect to checkout was activated if you select the option to add to cart in woocommerce->products.
