Troubleshooting Modmath 4.0: App Not Loading or Working Correctly

If Modmath is not loading, features are missing, or something looks wrong, try the steps in this article.

 

The App Won't Load

1. Check your internet connection. Modmath requires an internet connection to load. Make sure you are connected to Wi-Fi or cellular data.

2. Try a different browser. We recommend Google Chrome or Microsoft Edge. If Modmath is not loading in your current browser, try opening it in Chrome.

Safari users: some versions of Safari have restrictions on cookie handling that can prevent sign-in from completing. If you see a sign-in loop or a blank screen after signing in, try Chrome.

3. Clear your browser cache. Stale cached files can cause loading problems.

• In Chrome: Settings > Privacy and Security > Clear browsing data > Cached images and files.

4. Disable browser extensions. Ad blockers and privacy extensions can sometimes interfere with Modmath. Try disabling extensions temporarily and reloading the page.

5. Check for browser updates. Make sure your browser is up to date. Modmath uses modern browser features that may not work in older versions.

Signed In but Redirected Back to Sign-In

This usually means your session has expired or your browser is blocking cookies.

1. Make sure cookies are enabled for modmath.com.
2. If you use Safari, try Chrome instead.
3. Sign out completely, clear cookies for modmath.com, and sign in again.

"Your email is not verified" Warning

If you see this message on your dashboard:

1. Check your inbox for a verification email from Modmath.
2. Click the verification link in the email.
3. If you don't see the email, check your spam folder.
4. If the link has expired, sign out and sign back in to trigger a new verification email.

Can't Save or Access Features

This happens when your subscription has expired or your seat has been removed.

Individual users: Go to Settings->Billing to check your subscription status and renew if needed.

School/organization users: Your access is managed by your school administrator. Contact them to check your seat assignment.

Canvas is Blank or Not Responding

1. Reload the page. Press Ctrl+R (Windows) or Cmd+R (Mac) to reload.

2. Check browser compatibility. The canvas requires WebGL support. Most modern browsers support this. If your IT department has disabled WebGL, contact them to enable it for modmath.com.

3. Clear site data as a last resort. If the canvas is completely broken and other steps haven't helped:

• Go to your browser's site settings for modmath.com.
• Clear all site data.
• Sign in again.

Work Has Disappeared

Workbooks are stored in the cloud and are synced regularly. Work can be lost if:

• Your browser crashes.
• Your network connection was interrupted.

If you you are not seeing a workbook you were working on try logging out and back in.
