# Troubleshooting

## An error has occurred and you have not been charged. <a href="#error-occurred" id="error-occurred"></a>

This is an error on Checkout. Something is wrong with the card number, user's location, CVV number, card exp date or another credit card issue. Check the transaction in Stripe. Go into the card details as to why it was declined.&#x20;

{% hint style="info" %}
This doesn't have anything to do with Upgrade.Chat other than we are returning an error message because the card was not able to be processed by Stripe.
{% endhint %}

## There was a problem loading checkout <a href="#checkout-loading-problem" id="checkout-loading-problem"></a>
