How to Troubleshoot Browser-Related Issues in Ninety

Browser caching, settings, and compatibility issues can sometimes cause glitches or display problems when using Ninety. This guide offers step-by-step solutions, including general troubleshooting, browser-specific tips, and advanced fixes for persistent issues.

Common causes of browser-related issues

  • Cached files interfering with app updates.

  • Incorrect browser or device settings.

  • Outdated browser versions.

  • Zoom or theme settings conflicting with Ninety's interface.

  • Browser extensions or pop-up blockers interfering with functionality.

  • Multiple browser tabs causing conflicts.

  • Timezone settings causing date display issues.

  • Corrupted or stale cache and cookies causing login errors or unexpected redirects.

General troubleshooting steps

To address common glitches caused by caching:

  1. Log out of Ninety.

  2. Close all Ninety tabs or windows.

  3. Clear your browser cache and cookies: open your browser's settings, select the option to clear browsing data, choose a time range of 7 days or "All Time" for a comprehensive clearing, ensure both cache and cookies are selected, then confirm.

  4. Restart your browser completely and log back into Ninety.

Advanced troubleshooting for persistent issues

If clearing your cache doesn't resolve display or functionality problems, try these steps.

Verify browser and device-specific factors:

  • Switch to a different browser (if using Chrome, try Edge, Firefox, or Safari) to determine whether the issue is browser-specific.

  • Test in incognito or private browsing mode to bypass stored cache and extensions.

  • Check whether your device is set to dark mode or another theme that could override Ninety's appearance.

  • Test on another device to determine whether the issue is isolated.

  • Disable browser extensions temporarily, as extensions or pop-up blockers can interfere.

Address persistent display and loading issues:

  • Update your browser to its latest version.

  • Ensure your browser window is maximized and set to 100% zoom (reset with Ctrl+0 or Cmd+0).

  • Clear site-specific data for Ninety. In Chrome, go to chrome://settings/content/all, search for "ninety.io," and delete the stored data.

Alternatively, you can navigate through Chrome’s menu: go to SettingsPrivacy and SecuritySite SettingsView permissions and data stored across all sites, search for "Ninety," and delete the stored data.

Check for multiple tab conflicts:

  • Close all Ninety tabs except one.

  • Log out and back in using only a single browser tab.

  • Avoid opening multiple Ninety sessions simultaneously.

Browser-specific troubleshooting

Chrome (recommended browser). Chrome provides the best experience with Ninety. If issues persist: confirm Chrome is fully updated, clear cache and cookies for Ninety, try incognito mode to test extensions, reset Chrome settings (Settings > Advanced > Reset and clean up), and disable conflicting extensions.


Safari and other browsers. If Ninety works in one browser but not another: compare browser versions and update as needed, check browser-specific extensions or settings, clear browser-specific cache and cookies, and test with extensions disabled.

Troubleshooting specific issues

Login issues caused by browser cache or cookies

If you are experiencing login issues on Ninety, such as being redirected to the “Set up Your Company” page, seeing a spinner, or receiving a “can’t find this person” error, the problem is often related to corrupted or stale browser cache and cookies. To resolve these issues:

  • Use an Incognito/Private Browsing Window: This starts a fresh browser session without using saved cookies or cached data. If login works in incognito mode, proceed to clear your browser’s cache and cookies in the regular window.

  • Clear Browser Cache and Cookies: Remove outdated or conflicting data by clearing your browser’s cache and cookies. After clearing, fully close and reopen your browser before attempting to log in again.

  • Try a Different Browser: If clearing cache and cookies does not resolve the issue, try logging in using a different browser to confirm whether the problem is browser-specific.

For detailed instructions on clearing cache and cookies in Chrome, refer to the "Browser-specific troubleshooting" section.

Billing and payment loading problems.

If you experience endless loading when trying to select plans or access billing, try incognito mode, clear cache and cookies for Ninety, ensure pop-up blockers aren't preventing Stripe payment portal access, and try a different browser.


Knowledge Portal content not loading.

If 90 Resources or other Knowledge Portal content appears blank, clear your browser cache for "All Time," test in a different browser, ensure JavaScript is enabled, and check whether ad blockers are interfering.


To-Do and Issue detail loading problems.

If clicking on To-Dos, Issues, or other detail cards causes blank screens or loading loops, clear cache and cookies for all time periods, close all browser tabs and reopen Ninety in a single tab, try incognito mode, and check your timezone settings if dates appear incorrect.

Timezone and browser optimization settings

If you're experiencing date-related issues (such as To-Dos showing incorrect dates):

  1. Navigate to User Settings by clicking your name in the left navigation.

  2. Uncheck Set Timezone Automatically if it's enabled.

  3. Manually select your correct timezone.

  4. Clear cache and cookies after making changes.

  5. Log out and back in to apply the new settings.

For the best Ninety experience, use Chrome as your primary browser, keep it updated, disable unnecessary extensions, ensure JavaScript is enabled, and allow pop-ups for ninety.io if using payment features.

When to contact support

Contact support if you continue experiencing issues after trying these steps, especially if problems persist across multiple browsers and devices, error messages aren't resolved by cache clearing, or billing portal problems prevent subscription management. When contacting support, please include your browser name and version, operating system details, specific error messages or screenshots, and which troubleshooting steps you've already tried.
