I've been storing HTML files in a sharepoint 2007 library for about 2 years now and using version history. Recently sharepoint has started displaying "cannot find file" errors when clicking on the HTML files in the document library view. I've pinpionted the issue to this line in our HTML file that contains a long string of CSS classes. <li class="navigation-inner-container navigation-tab-small background-gradient-light pie top-right-rounded-corners-small yuimenubaritem-hassubmenu yuimenubaritem divider-left"> When the above line is removed and the file checked in, it then displays fine. What could possibly be causing sharepoint to display 'file not found' when the above line is included in the HTML file?

Hi acMac, Could post you HTML file code here, in order to let us analysis this issue with more information? ThanksRegards, Daniel
