My site has 3 skins - Home - section home and Page - all were working fine on Friday but today the home skin completely broken. The home page displays with no css and looking in the source view I see this 

<div id="wrapwebsite">

    <div id="wrapheader">
     <h1 class='art-Logo-name art-logo-name siteheading '><a class='siteheading' href='http://localhost:52231/Default.aspx'></a></h1>
     <a href='#startcontent' class='skiplink'>Skip over navigation</a>

just after the Sys.WebForms.PageRequestManager._initialize block

where I expect to see

<div id="art-page-background-middle-texture">
   <div id="art-main">
        <div class="art-sheet">
        <div class="art-sheet-cc"></div>
        <div class="art-sheet-body">           
               <div class="art-header"> ... etc
                <div class="art-header-clip">                

If I switch the skin for the home page it all works fine but with the wrong header content.

I guess I have deleted some setting or file but cannot figure out what. Consistent on all browsers. Checked the recycle bin - nothing deleted. All I had done this morning was changed some HTML inside the slider in the home layout.master - have tried reversing the edits - no difference.

Any clues where to look - ?? I guess I will need to remake the skin unless someone has seen this before.

Thanks - the permissions are the same on skin that works and the one that doesn't. Have done a line by line diff on all relevant files and can see nowt. Its not the slider element as the skin still fails when that is commented out. It is all the CSS that isn't loaded so I was suspecting the style.config but it seems fine. Going to jyst recreate it from scratch this morning - ...

The only thing I know changed was that WinUpdate installed a couple of .NET 4 patches yesterday morning and the W7 SP1 but as all th eother skins work fine I cannot see how that could be relevant.

Cheers
