OSM_COUPON + PAYPAL Error - by: Loic

Hello,
I have a problem with my website.

In fact, on this page bscnews.fr/offre-premium-mag/sign-up.html when you enter a coupon and you select "Paypal"' this error below appear.

ReferenceError: langLinkForAjax is not defined
calculateSubscriptionFee() paymentmethods.js:210
onchange() sign-up.html:1

Do you have a solution ?

Thanks

Best Regards.

Loïc.
