Solution for "server error during URL Processing" and "HTTP 500 error"

In fact, this situation is caused by the unclear expression of the problem.

The following describes the causes of these two errors:

1. An error occurred while processing the URL. Please contact the system administrator!
As long as the "send text error message to client" option is selected in the IIS settings on the server, any errors on the page will display "server errors during URL Processing, contact the system administrator!" In this case, you need to contact the server administrator to remove this option, or download the website to a local device for debugging. People who seek help from this information alone cannot get any help, because they cannot see detailed error information.

2. HTTP 500 Error

The origin of this error is as follows. If you select the "show friendly HTTP Error message" option in IE advanced settings, any error will also display an HTTP 500 error. Therefore, remove the check box before the friendly HTTP Error message displayed in your IE advanced settings. The error details are displayed, which helps you determine the error.
