Are you a regular user of Google Slides? Have you ever come across a puzzling “error 150”? This error can interrupt presentations, and for many, it’s not always clear why it appears or how to resolve it. However, there’s no need to fret. In this guide, we’ll dive deep into the reasons behind error 150 in Google Slides and provide a step-by-step guide to fix it. Let’s get started.

Reasons behind error 150 in Google Slides

  1. Internet Connection Issues: The most common culprit behind error 150 is an unstable or weak internet connection. Google Slides relies heavily on the internet to function smoothly. When the connection is lost or weakened, operations can halt, causing the error.
  2. Cache and Cookies Overload: Your browser stores cache and cookies to speed up browsing. However, an overload can cause conflicts, leading to errors like the 150 in Google Slides.
  3. Browser Compatibility Issues: Not all browsers support Google Slides equally. If you’re using an outdated or unsupported browser, you might encounter error 150.

How to fix error 150 in Google Slides?

Fix 1: Clearing Cache and Cookies

One of the primary culprits behind error 150 in Google Slides is an overloaded cache and cookies. These data bits accumulate over time as you browse the web, aiming to speed up your browsing experience. However, an excessive buildup can lead to conflicts and errors. Here’s a step-by-step guide to clearing cache and cookies to resolve the issue:

By following these detailed steps and clearing out the accumulated cache and cookies, you’ll likely find that error 150 in Google Slides becomes a thing of the past. This solution is effective in resolving conflicts caused by an overloaded browser, allowing you to seamlessly create and present your slides without any interruptions.

Fix 2: Update or Change Your Browser

If clearing cache and cookies didn’t do the trick, the next step is to consider your browser’s compatibility with Google Slides. Outdated or incompatible browsers can lead to errors like error 150. Here’s a comprehensive guide on updating or changing your browser:

  1. Check Your Current Browser: Start by identifying which browser you’re currently using to access Google Slides. Common browsers include Chrome, Firefox, Safari, Edge, and more.
  2. Check for Updates: If you’re using a popular browser like Chrome or Firefox, updates are often automatic. However, it’s a good practice to manually check for updates. Look for the three dots or lines in the top-right corner of the browser, and navigate to the Help or About section. Here, you’ll find the option to Check for Updates. If an update is available, follow the prompts to install it.
  3. Update or Switch: If your browser is up to date and the error still persists, consider switching to a different browser. For example, if you’re using an older version of Internet Explorer, it’s advisable to switch to a more modern browser like Chrome or Firefox, which are known for their compatibility with Google services.
  4. Download and Install: To switch or update your browser, go to the official website of the browser you want to install. For instance, if you’re switching to Chrome, search for “Google Chrome download” in your preferred search engine. Download the installer from the official website and follow the installation instructions.
  5. Transfer Bookmarks and Data: If you’re switching browsers, you might want to transfer your bookmarks, saved passwords, and other data. Most browsers offer the option to import data from other browsers during the installation process.
  6. Access Google Slides: Once you’ve updated your browser or switched to a compatible one, open a new tab or window and navigate to Google Slides. Log in to your Google account and check if error 150 still occurs.

Browser updates often include bug fixes and improved compatibility, which can significantly enhance your overall online experience, including creating and presenting slides using Google Slides.

Fix 3: Log Out and Log In

Sometimes, resolving error 150 in Google Slides can be as simple as refreshing your session by logging out and then logging back in. Glitches and temporary issues within your Google account can lead to this error. Here’s a step-by-step guide on how to perform this quick fix:

  1. Logout from Google Account:
    • Open Google Slides if it’s currently open.
    • Look for your profile picture or initial in the top-right corner of the screen. Click on it.
    • In the dropdown menu, click on Sign Out or Log Out.
  2. Close Browser Completely:
    • After logging out, make sure to close the browser tab or window completely. This ensures that any lingering session data is cleared.
  3. Reopen Browser and Google Slides:

By performing a log out and log in sequence, you’re essentially resetting your session, which can clear out temporary glitches causing error 150. This method is especially effective if the error is tied to your Google account rather than the browser or internet connection. It’s a quick and hassle-free fix that you can try before exploring more complex solutions.

Fix 4: Try Another Device

If you’ve exhausted the previous fixes and error 150 in Google Slides still persists, it’s time to consider whether the issue is specific to the device you’re using. Sometimes, the problem might be related to the hardware or software configuration of that particular device. Here’s how to troubleshoot this issue by trying a different device:

  1. Choose an Alternative Device:
    • Identify another device that you can use to access Google Slides. This could be a different computer, laptop, tablet, or even a smartphone.
  2. Ensure Stable Internet Connection:
    • Before proceeding, make sure the alternative device has a stable and reliable internet connection. A poor connection can lead to similar errors.
  3. Access Google Slides:
    • On the alternative device, open a web browser and navigate to Google Slides.
    • Log in to your Google account and try to open the same slide that was causing the error on the previous device.
  4. Observe for Errors:
    • Pay close attention to whether error 150 occurs on the alternative device as well.
  5. Compare Results:
    • If the slide opens without any issues on the alternative device, it indicates that the problem might be specific to the initial device you were using.
  6. Device-Specific Solutions:
    • If you determine that the issue is indeed tied to the initial device, you can explore device-specific solutions. This might include updating the device’s operating system, checking for browser compatibility, or troubleshooting any hardware-related issues.

Pro Tip: Testing Google Slides on another device not only helps identify device-specific issues but also allows you to continue your work without interruptions.

By trying a different device, you can narrow down whether the issue is related to your Google account, browser, or internet connection. This step is particularly valuable when all previous fixes haven’t resolved the problem. If the alternative device works smoothly, you can focus your efforts on diagnosing and addressing any device-specific issues on the initial device you were using.

  6. Return to Google Slides:
    • After adjusting permissions, go back to Google Slides and attempt to open the presentation that was previously showing error 150.
  7. Re-check for Error 150:

Regularly reviewing and managing your account’s permissions ensures not just smooth functionality but also enhances security.

Fix 7: Disable Browser Extensions

One lesser-known factor that might be causing error 150 in Google Slides is a conflict with a browser extension or plugin. Some extensions, especially those that interact with web content or modify web pages, can interfere with Google Slides’ operation. Here’s how you can troubleshoot and resolve potential extension-related issues:

  1. Access Browser Extensions/Plugins:
    • Open your web browser and navigate to the extensions or plugins section. This is usually found within the browser settings or options menu.

  4. Reopen Google Slides:
    • After disabling an extension, go back to Google Slides and attempt to open the problematic presentation.
    • If the error persists, return to the extensions page, re-enable the previously disabled extension, and then disable another one. Repeat this process until you’ve identified the culprit.
  5. Update or Remove Problematic Extension:
    • Once you’ve identified the extension causing the issue, consider updating it (if an update is available) or removing it altogether. Some extensions might have known conflicts with certain web applications and the developers often release fixes in updates.
  6. Check for Error 150:
