Javascript error on Dreamweaver CS3 load

I get the following error when i start Dreamweaver after I just installed the CSS Sculptor. On the first install it crashed dreamweaver....second install worked but now the error...

While executing onLoad in WAMemento_onOpen.htm, a JavaScript error occured....
hit OK and then the same popup comes up a few more times...

and then DMWR crashes...

How do I clear this?

Hi I'm getting the same thing happen today despite not installing any new extensions. Dreamweaver was working perfectly yesterday but now I can't use any of my extensions and I'm getting messages just like you.

You could try disabling Memento from the Edit/Webassist preferences

Under memento - choose - Show on Dreamweaver start up never
Also disable the RSS feeds.

I say this because I have just looked in my support history as I had this problem once before (but when installing one of the extensions like yourself) and it was one of the suggestions.

However, the problem was only resolved when one of the support team remotely took over my computer and I can't now remember what they did.

Just found this on this forum which may help. I'm going to try it.

Sal, just to let you know, the above has worked for me so might be worth a shot.

Yes, try deleting the Dreamweaver Cache file from the users configuration folder. more specifics can be found here:

Cleared the cache in Dreamweaver and it is fixed. Found the solution in an old post by Mr. Chu....cool. Thanks everyone for the reply.
