Hi Christian!
Thanks for reaching out to us. I’d be happy to help you with that.
First, let me note that we only give direct support for our license holders via these forums as we state here > https://theeventscalendar.com/knowledgebase/what-support-is-provided-for-license-holders/ and it may take us between 24-48 hrs before we respond to a post. It generally is significantly faster than that, but we ask to be patient during times with higher demand in our forums.
All the checkout process is handled by WooCommerce, so you’ll find all the settings by going to your wp-admin > WooCommerce > Settings.
If you want to change the Check payment information displayed in the checkout, you’ll find that option by going to wp-admin > WooCommerce > Settings > Checkout tab > Check Payments section. In there, you will see a screen like the following https://cloudup.com/cdu62Q9Piw9
You can find out more about the WooCommerce settings in their documentation here > https://docs.woocommerce.com/documentation/plugins/woocommerce/
And you’ll find all about the payment options here > https://docs.woocommerce.com/documentation/plugins/woocommerce/getting-started/sell-products/core-payment-options/
I hope that helps! Is there anything else I can do for you? Let me know.
Best,
Victor
