Re:
Hi Daryl,
Yo should copy the files from: C:\Users\Username\AppData\Roaming\Adobe\Dreamweaver CC\LocalLanguage\Configuration\Connections\Scripts\PHP_MySQL\_mmDBScripts, to the _mmServerScripts directory of your site.
And later, set the files in your site as "read only" because dreamweaver cc try to delete the files. I don´t know why. Many hours to find this solution, but it works for me.
Them, dreamweaver and server behaviours will work, but not data assist wizard :(, i use dreamweaver CS6 only to use data assist wizard. Only the wizard fails.
Regards!
