I am just started receiving this error message from pages that had been running successfully and I was able to edit the menus. Pages based on a template that uses the menu open after cancelling these error messages:
Making this change would require changing code locked by a template or translator. This change will be discarded.
I cancel this 3 times and then the message below appears.
While executing onload, the following javascript error(s) occurred:
At line 526 of file 'C:\Program Files(x86)Adobe\adobe Dreamweaver cs5\configuration\commands\dmxUpdarehead.htm":The object is not currently contained in a document.

Can you tell me how to fix this please?

Hello,

Does this error appears after updating the product?

Hi Teodor:
DMXzone messages were popping up every time I opened Dreamweaver. I seem to remember updating but cant remember which programs were included. I installed CSS Nav menu in Dreamweaver on the 16/02/2012 added it to the site around 21/02 and it funcioned perfectly until around the 1/3. If an new update was available at that time I would have installed it.

Hello Stephen.

Please clear your DW cache file :
Clearing Dreamweaver's cache
Reinstall the extension using a fresh downloaded copy from our product page:
Universal CSS Navigation Menu product page
