Dreamweaver 8 template not updating
Here's where Dreamweaver CS5 shines in helping you automate the task of creating and maintaining a multi-page website.
You do not need to manually go through every page to make those design changes.
There is a logo and a navigation menu in the left column, and the content specific to each page is housed in the right column.
This common design is the result of my basing all my pages on a template containing all the above elements (logo, navigation menu, 2 column layout, etc).
You don't update a Dreamweaver template with plesk.
You do it with Dreamweaver, which then alters all files stored on your pc using the template. Plesk, or any other control panel, has nothing what so ever to do with a dreamweaver template, only Dreamweaver uses it.
