Credit Card form won't load

[tipofloe]

Hello,

I am trying to integrate the payment gateway but during checkout when I select credit card/Heartland, the page gets "whited out" and then it "freezes".

The error message I get is:

Uncaught SyntaxError: Unexpected token < in JSON at position 2
at JSON.parse ()
at Object.success (/site/pub/static/version1492465544/frontend/theme/theme/en_US/HPS_Heartland/js/view/payment/method-renderer/heartland-method.js:75)

at Object.fireWith [as resolveWith] (jquery.js:3211)
at done (jquery.js:9310)
at XMLHttpRequest.callback (jquery.js:9720)

I also get an error report:

I've reached out to Heartland and I've been told that I can get around the error by turning off display_errors within the PHP config. I have verified that display_errors is turned off inside php.ini in the webroot folder. Is there another location that I need to verify to turn this off? I've run a search but there was only one php.ini file.

Anyone come across this type of error message? In any case, I would greatly appreciate if anyone could shed some light into this.

Thank you!

Hi @tipofloe! Apologies for the inconvenience here.

We are aware of this and are working on a fix. If disabling display_errors isn't working, disabling error reporting for warnings should do the trick until we can get our proper fix out.
