JavaScript Error

When I double click on the Universal Email Server Behaviour so that I can edit my UE settings I get a JavaScript Error.

I have attached a screen shot of the error message.

Just want to make sure I have this right before I start as I have a large number of extensions installed!

Step 1 - I tried already
Step 2 - I need to change the name of the configuration folder AND delete and reinstall all of my extensions?

If deleting the cache didn't help, then I would only go with re-installing a large number of extensions as a last resort. You have to determine which path saves the most time and trouble.

Before renaming the configuration folder, try a couple of tests to determine if it is necessary:

1) Uninstall Universal Email form the Extension Manager and install the latest version that is available from the download center. After reinstalling, delete the cache file again before opening Dreamweaver to see if the error persists when trying to edit that file.

2) Create a new page and add only Universal Email to it with a very simple message body. Save the page, close Dreamweaver and open it again and try to edit the Universal Email server behavior on that page to see if the error is specific to the page or a problem with the install.
