Hi @Hong,
If you get such an error even when detailed errors are enabled, right-click anywhere in the browser window and select Inspect (or press F12). This will open the developer tools in a browser window. Now, click on the Console tab. The actual errors thrown by the web server will be displayed.
If the console prompts: the server responded with a status of 500
, then you need to enable Failed Request Tracing to further understand the exact cause of the 500 error.
Try to reproduce the issue and open the newly generated XML log file. You will see detailed error messages and sub-status codes to help you locate the problem.
