Although I can't read Chinese, that error message looks as though it's telling you there's either no testing server or that the server doesn't map to the URL.

Thanks for your reply
I really have a testing server(XAMPP) and that the server really map to the URL
I have been pressing the F12 and the Pages can appear normal
I'm not the first time to use DW
when I use the DW CS5 OR 6，that the situation never been happened
only use the DW CC，This situation appears
you can use your DW CC to try once again，and you will know my question
In that case, I'm sorry I can't help you. I stopped using Dreamweaver's server behaviors many years ago, and I don't have them installed in Dreamweaver CC.
just thank you~
I've found the answer, and tested
Copy the following path MMHTTPDB.php with mysql.php
C: \ Users \ user \ AppData \ Roaming \ Adobe \ Dreamweaver CC \ (wanna see is what language) \ Configuration \ Connections \ Scripts \ PHP_MySQL \ _mmDBScripts
To this path under
C: \ your web server \ folder name of your site \ _mmServerScripts
In this way, then you can successfully connect
