Kaspersky Internet Security and Total Security blocks the Stripe PopUp if (default) the finance module is activated!
Who should solve this? S2meber or Stripe?
Users cannot check out if Internet Security / Total Security is installed as default.
The popup itself will open - but the credit card data will not be transferred to Stripe. Deactivating the online banking/payment module solves this.
SSL cert is fine (it’s not an EV cert though).
