There is some jquery automatically added to pages that creates YUI tabs where they need to be based on some css class names. The YUI and jquery scripts are loaded from the google CDN so the only reason I could see getting errors is if your machine is not connected to the internet and it can't load the javascript.

Other than that if you have script debugging enabled in IE it may throw errors at debug asserts that would not happen under normal conditions. If you turn off script debugging in IE and you still get errors then its really an error not just something from debug statements, and again that would seem like its not loading the scripts.

If you don't have internat acess on that machine then you can set UseGoogleCDN=false in Web.config or user.config but then you'll have to get your own copy of YUI and jQuery and put them in the correct locations for local use.

I cannot produce the problem locally or on any of my sites using IE 7

Hope it helps,

Hi,

YUI tabs are used extensively in mojoPortal at the moment. Even if you set AlwaysLoadYuiTabs=false, it will still load them where they are used in admin and edit pages. It does not mean never load YUI tabs.

Make sure you have not changed this to false:

<add key="UseGoogleCDN" value="true" />

With this as true it will load the YUI scripts from google cdn which is why you must be connected to the internet.

The error seems like it is not loading the YUI scripts or they have an incorrect url. You should view the source of the rendered page to determine where the scripts for YUI are loaded from and whether the url is correct or not. If the script fails to load you will get errors.

You can disable all of YUI like this:

<add key="DisableYUI" value="true" />

but then you will have a very ugly admin UI

Hope it helps,

Joe
