What Browsers do you need to use your Account

Updated 2 min read


CPR Enroll is a modern web application built as a Single-Page Application (SPA). The admin dashboard at dashboard.cprenroll.com and the student registration pages at classes.cprenroll.com both require a current, JavaScript-enabled web browser to function correctly.

Supported Browsers — Admin Dashboard

For the best experience managing your account, use one of the following browsers on a desktop or laptop computer:

BrowserMinimum VersionRecommended
Google ChromeVersion 100+✔ Latest stable release
Mozilla FirefoxVersion 100+✔ Latest stable release
Microsoft EdgeVersion 100+✔ Latest stable release (Chromium-based)
Apple SafariVersion 15+✔ Latest stable release (macOS only)

⚠ Internet Explorer is not supported. Microsoft Internet Explorer (IE 11 and below) is not supported and will not render the dashboard correctly. Use Microsoft Edge instead.

Mobile Browsers — Admin Dashboard

The admin dashboard at dashboard.cprenroll.com is optimized for desktop and laptop screens. While it may load on a mobile browser, some features (tables, forms, and multi-column layouts) are difficult to use on small screens. We recommend managing your account on a desktop or laptop for the best experience.

Mobile Browsers — Student Registration Pages

The student-facing registration pages at classes.cprenroll.com are fully mobile-responsive. Students can browse classes, register, and pay on any modern smartphone or tablet browser without any issues. The embedded registration widget also auto-adjusts to the container width on mobile.

Required Browser Settings

  • JavaScript must be enabled. CPR Enroll is a SPA — it loads and renders entirely through JavaScript. If JavaScript is disabled in your browser, you will see a blank screen or an "Initializing..." message and the app will not load.
  • Cookies must be enabled. The platform uses session cookies to keep you logged in.
  • Pop-up blocker. Some browsers block the Stripe payment window as a pop-up. If students report that the payment window does not open, advise them to allow pop-ups for classes.cprenroll.com.

Troubleshooting a Blank or Frozen Screen

  1. Press Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac) to do a hard refresh and clear the browser cache.
  2. Try opening the dashboard in an Incognito / Private browsing window to rule out a cached session issue.
  3. If the problem persists, try a different supported browser.
  4. Contact support at [email protected] if the issue continues.
