I know this isn&#039t really an ASP question but I hope someone can help. I have a web site I designed in Visual InterDev. All of a sudden when I try to open up the solution in InterDev and open up a page I get this message:<BR><BR>Unable to open web project "ProjectMgmt". An HTTP error ocurred. The Server could not complete your request. Cant your Internet Service Provider or Web Server Administrator. Make sure that the server had the FrontPage Server Extensions installed, and that the web application exists on that server.<BR><BR>I can open up other solutions without a problem. This site is still up and running and I can edit pages outside of the project by opening them up through Windows Explorer. So I don&#039t think that I have a problem with FrontPage Server Extensions and the application definately does still exist.<BR><BR>Anybody have any clue why I am getting this message and how to fix it.<BR><BR>Thanks<BR>
