How to fix ActiveXObject not defined error

Today, I will discuss how to fix the ActiveXObject not defined error.

Disabling Error Debugging and Notifications

To fix the ActiveXObject not defined error, you can disable error debugging and notifications. In Google Chrome, you can do this by opening the developer tools with the F12 key, going to the “Console” tab, and checking the “Disable cache” option. This will prevent error notifications from popping up. Additionally, you can disable error debugging by going to the “Sources” tab, finding the relevant JavaScript file, and adding debugger; to the code where you want to stop debugging. This will pause the code execution at that point.

Contacting Website Administrators

To fix the ActiveXObject not defined error, contact the website administrators to check if they can provide a solution. Explain the issue you are facing in detail and ask if they have any recommendations or updates to the website’s code. If the error is related to a specific Java applet or plug-in, inquire about potential conflicts with your browser or operating system. Make sure to mention if you are using Google Chrome, Internet Explorer, or any other web browser. Additionally, ask if they have tested the website for cross-browser compatibility and if they have implemented any specific features that may be causing the error.

Understanding Access Blockage Reasons

To fix the ActiveXObject not defined error, it’s crucial to understand the access blockage reasons. This error typically occurs when the browser blocks the use of ActiveX controls due to security concerns.

Check if the website is using HTTPS instead of HTTP to ensure secure communication. Additionally, verify if the site is added to the trusted sites list in Internet Explorer to allow ActiveX controls to run without issues.

It’s also important to update Java and ActiveX components to the latest versions to address any compatibility issues. By clearing the browser cache and cookies, you can ensure that the browser is not blocking the ActiveX controls due to stored data.
