SOLVED *** Problem with Display manager not displaying correctly on cart page.
After searching the forums I came across a post that said to delete a file from your configuration folder under dreamweaver.
I guess deleting this file helps solve a lot of issues that come up. The post says if your software is acting funny (common issues with DW) that your supposed to locate the WinFileCache.dat file and delete it.
Where I went wrong was I didn't notice that you were supposed to have DW closed while you delete the file. Aha, I didn't do that. So I uninstalled and reinstalled ecart6, and this time when I located the file I made sure to close Dreamweaver before I deleted the file.
So I went through the motions of creating a new ecart object and was able to add the display manager to my cart page.
So far so good, I just wanted to share my solution in case anyone else is having the same issues.
