JavaScript Error

I'm getting a JavaScript error when attempting to insert CSS Button on any form. The error is:

"Error editing for button string:
Error: getDocumentDOM: Argument number1 is invalid;"

have you tried Deleting the Dreamweaver Cache file from the users configuration folder:
http://www.webassist.com/community/tutorials/view_tutorial.php?tid=95


if you continue to have a problem, please provide details about your system:

What Version of DW?

What Extensions including the version numbers are installed?

What is your OS?

Deleting the Cache file didn't work.

I have Dreamweaver CS6

My extensions are:

Design Extender 1.1.1
WebAssist Free Tools 1.0.2
Data Bridge 1.1.3
eCart 5.0.3

My OS is: Win 7

Design Extender 1.1.1 and eCart 5.0.3 are out of date.

uninstall those 2, then install eCart 5.0.7 followed by Design Extender 1.1.3

Ok, I uninstalled the two extensions and installed the newest versions of same.
When installing the new versions I get a prompt that says something to the effect of: "The files on your system are newer than the files you are installing, do you want to replace the files on your system with these files" (not an exact quote). I choose "Yes to All". I hope that is the right choice.

Anyway, that didn't help the JavaScript error. I'm still getting the error.

here is an updated copy of the configuration/shared/webassist/buttonstyler/ButtonStylerShared.js file that should correct the problem.

for help locating the users configuration, see the common installation issues page:

Excellent! That fixed it!
Thanks so much!
