The Adobe Dreamweaver CC MySQL connection was reported with a 404 error and gave the following two tips:
1) There is no test server running on the server machine.
2) The test server specified for the site is not mapped to Http://localhost/_mmServerScripts/MMHTTPDB.phpURL. Make sure that the URL prefix is mapped to the root of your site.
Online over a bunch of websites, tossing for two or three days, found that can be resolved as follows:
1) First to configure the MySQL access password in http://localhost/security/index.php (I use XAMPP, can also be configured in other ways depending on the situation)
2) will "C:\Users\Administrator\AppData\Roaming\Adobe\Dreamweaver Cc\zh_cn\configuration\connections\scripts\php_ Mysql\_mmdbscripts "
Two files under "mmhttpdb.php" and "mysql.php",
Copy to the "C:\xampp\htdocs\_mmServerScripts" folder.
3) then restart Dreamweaver and connect again.
