Authorize.net credit card module/plugin won't allow entering of a credit card, F

-- Error-message(debug-mod must be tuned on) -- : The Aurthorize.net Credit card module refreshes but it won't show the form to enter credit card.

We have processed transactions without issues until last week, but today we received a message that the customer could not find a form to enter their credit card after creating an account and purchasing a product.

In going over things, I realized our subscription expired in April 2025. I will be renewing it as soon as my client sends me their credit card or has time to go online with zoom so I can renew hikashop, but that cannot be the reason since we have had transactions clearing until recently.

What happens now is that after login or after creating an account we get this message:

Credit Card PBF
You can pay by credit card using this payment method
You chose the payment method: Credit Card PBF

Clicking on "Pay" or "Continue" just refreshes the page and there is no form to enter the credit card.
I also turned on Paypal Checkout, but that too only refreshes and never goes to paypal to pay.

Again, everything worked fine as of last week.
I am checking Authorize.net in case something went wrong there, but it all seems in order. I'll have my client call them to confirm. Meantime there is no available payment method on the website.

PS: The Authorize.net plugin is named
Hikashop Authorize.net Payment Plugin

I cannot find out if this is the same plugin as this one: www.hikashop.com/marketplace/product/150...e-js-by-obsidev.html

I am having my client call authorize.net to make sure nothing is broken over there.

Thank you very much. I need to upgrade Hikashop anyway. I am just waiting for my client to find the time to go online and pay Hikashop as well as purchase the new payment plugin.

I already tried some of the solutions you outlined, but not all of them by a long shot. In dev tools there is no form at all, so it's not something the template is hiding. Also, it worked fine last week until it didn't. We processed several payments a day before this issue popped up, so something bad happened, but not something I or my client did as neither of us logged into the site. The only person that logged into the backend was my client's brother and he only knows how to process orders. He never touches anything else, but who knows? Maybe the cat walked over his keyboard.

I am going to try the suggestions you proposed and hopefully I'll be able to buy and install the new authorize plugin and that will solve the issue. I am never that lucky, but maybe today is my lucky day.

Thank you again.
