You have just installed the PrestaShop Checkout module, you have connected your PayPal account, but the module does not appear at the payment stage? Here are some verification steps to follow:
1 - Go to the module configuration and make sure that the desired payment methods (for example Bancontact, and credit card payment) are activated.
If they are properly activated, but you do not see any payment method from PS Checkout on the front of the store, proceed to step 2.
2 - Go to the Payment > Preferences section of your back office and ensure that the PS Checkout module is checked for transactions in the relevant currency, for the relevant countries, as well as for the relevant delivery methods.
For example, if the module is not checked for the country Belgium, and you are selling in Belgium, your Belgian customers will not see the module appear at the payment stage.
3 - You can also clear the cache of your PrestaShop store, this allows you to ensure that the failure to display the module at the payment step is not due to the fact that the temporary files of your store have not been updated.
4 - If you have just installed the module and the configuration seems correct, but the payment methods are still not displayed, simply try reinstalling the module. In many cases, this simple manipulation may be sufficient to resolve the issue.
