before applying the display manager, make sure you have completed the following:
1) Create a new site in Dreamweaver, on the testing server tab of the site definition, select PHP/MySQL as the server language.
2) Create a new PHP page and save it to your site.
3) Open the new PHP Page, then create a new eCart object. Go to Insert ->WebAssist -> eCart -> eCart Object.
If you continue to have problems, please post back the following information:
Site Settings - Local Info tab:
what is the Local Root Folder?
What is the HTTP Address
Site Settings - Testing Server Tab:
What is the Server model?
What is the Access?
What is the Testing Server Folder?
What is the URL Prefix?
can you send a copy of your WA_eCart folder so I can try to recreate the problem.
