If you are experiencing issues with the submit buttons on questions in an MIT xPRO course/program, there are a few steps you can take to debug your web browser:
-
Ensure that you are using the most up-to-date version of Google Chrome or Mozilla Firefox. Using outdated versions may result in compatibility issues with the courseware.
-
Verify that both JavaScript and Cookies are enabled in your browser settings. Some functionalities of the courseware rely on JavaScript and may not work properly if it is disabled. Additionally, certain features may require the use of cookies, so make sure they are enabled as well. Note that some corporate IT policies may disable third-party cookies by default, so you may need to adjust your settings accordingly.
-
Clear your browser cache or other browsing data. Accumulated cache or browsing data can sometimes interfere with the proper functioning of the courseware. Clearing this data can help resolve display and functionality problems. However, ensure that you comply with any local IT policies when making these changes.
If you continue to experience these issues even after following these steps, please submit a request to our support team. In your request, include the URL where you are experiencing the issue, specify your operating system and web browser version, and provide a screenshot if possible. This information will assist us in reproducing and resolving the bug you encountered. You can email your request to support@xpro.mit.edu.
