”Failed to load Stripe.js”

The billing page loads Stripe.js from js.stripe.com. If your browser or an extension blocks it, the page can’t render the checkout form. Fix
  • Whitelist *.stripe.com in your ad blocker / privacy extension.
  • Allow third-party scripts on platform.postiz.com.
  • Try a clean Chrome/Firefox profile to confirm it’s an extension issue.

​
Billing page is blank or throws errors

The billing page uses localStorage to cache plan state. In some private / incognito modes (Safari, Firefox strict mode) localStorage is null and the page crashes on access. Fix: open the billing page in a normal browser window.

​
Discount code doesn’t apply

Postiz validates discount codes server-side against Stripe. If apply fails, double-check:
  1. Spelling and case — codes are case-sensitive.
  2. The code hasn’t already been used or expired.
  3. The code applies to the plan you’re trying to upgrade to.
