Error message when opening a file using online MATLAB

I have several files I created saved to my MATLAB Drive using the online MATLAB. However,now when I try to reopen them, I recieve an error message. This is also happening when trying to open files I downloaded from the Teaching with MATLAB online training module. No files will open, including those I opened previously! How to do I fix this problem?

All files result in the same error message:

Error occurred setting content: TypeError: Argument 1 ('node') to Node.appendChild must be an instance of Node

Hi Tricia,

I understand that you are encountering an error while opening a file using MATLAB online.

The error message states, "TypeError: Argument 1 ('node') to Node.appendChild must be an instance of Node," suggests that there is an issue with the web application's interaction with the browser's Document Object Model (DOM). This is not an error with MATLAB code but rather with the web interface itself.

Here are some steps to troubleshoot and potentially resolve this issue:

• Refreshing the Browser as simply refreshing the browser can resolve temporary glitches with web applications.
• Clearing Browser Cache and Cookies as browser's cache can become cluttered, which might cause issues with web applications. Clearing the cache and cookies can often resolve these types of issues. This resolves the issue in most of the cases.
• There might be compatibility issues with the browser in use. Try accessing MATLAB Online with a different web browser to see if the problem persists.
• Browser extensions can sometimes interfere with web applications. Try disabling extensions, particularly those that manipulate web content or have access to web activity.
• Ensure browser is up to date. An outdated browser may have compatibility issues with newer web applications.
• Try restarting computer as it can resolve underlying issues that might be affecting the browser's performance.
• Open browser in incognito or private mode and try accessing MATLAB Online. This mode usually disables extensions and uses a fresh session, which can help identify if the problem is related to extensions or browser's session.
• If using MATLAB Drive Connector, make sure it is running properly and one is logged in with the correct MathWorks account.

Remember to save all the work before attempting these troubleshooting steps to avoid losing any unsaved changes.
