Hello，
Thank you very much for very fast reply and the suggestion.
I tried to update the .htaccess file, and then the whole website crashed， and I got the error message as below:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at webmasterexample.com to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
Could you kindly advise what else I could try? Thanks!
