Woocommerce not showing payment option on checkout

Hi,

I am new to creating websites and am not really very tech savy. I am really please that I have been able to design my own site and set everything up. I placed the site live and it all worked great for the first order but now woocommerce is saying ‘There are no payment methods available. This may be an error on our side. Please contact us if you need any help placing your order.’ It was working fine before as I have received all the emails etc to confirm the order went through. I have already tried to deactivate addons and it still didn’t work with them all deactivated. I am starting to go mad and don’t understand CSS etc so please be patent with me, I just want my site to work ?? Thank you in advance for any help you can give.
