Hi Dhivya,
Here are the followings things you can try to resolve the issue:
1. Reload the web page. You can do that by clicking the refresh/reload button, pressing F5, or trying the URL again from the address bar.
2. Clear your browser's cache. If there's a problem with the cached version of the page you're viewing, it could be causing HTTP 500 issues.
3. Delete your browser's cookies. Some 500 Internal Server Error issues can be corrected by deleting the cookies associated with the site you're getting the error on. After removing the cookie(s), restart the browser and try again.
If the above suggestions won’t resolve your issue, then it could be an internal server issue that a professional could solve.
Hope this helps!
