Hi Joe,
I have just upgarded to 2.3.9.7 my test & demo site (.NET 4.5), where I can test features and skins before the deployment to all production sites.

jQuery Tabs and Accordion don't work with a skin created with Artisteer 4.0
Other skins created with earlier Artisteer versions have no problems.
For your info, the skin includes a nivo slider in page header (which works fine). Can this affect the jQuery scripts ?

Please, note that with version 2.3.9.5, I changed the ScriptLoader in layout.master of all Artisteer skins as suggested:

<%--  <portal:ScriptLoader ID="ScriptLoader1" runat="server" /> --%>
<portal:ScriptLoader ID="ScriptLoader1" runat="server" IncludeJQueryMigrate="true" />

Any clues ?
(if needed I can zip and send you the skin to check how it works with jQuery UI)

Thanks.

Diego
