When customers check out using Striper, they receive this message:
"An unexpected error has occurred submitting your credit card to our secure credit card processor. This may be due to network connectivity issues, so you should try again (you won't be charged twice). If this problem persists, please let us know!"
Then it quickly reloads the page.
I use Striper on another ecommerce site that I own, with the same API Keys and is has not had this issue. I am updated to the latest version of WordPress and Woocommerce.
Please help ASAP!
Thank you --
