Subscription blog from Wix App not working

Unable to access to blog subscription payment page:

When I click the button, nothing happens. This will usually bring me to the payment page for my clients to pay, but this has stopped working.

I have already set up the payment page (published) with pricing and plan from the dashboard. I already had a few payments previously.

I am using Wix’s own app for blog subscription.

Any help will be greatly appreciated. Thank you.
