Hey all,<BR><BR>I have an Interdev project that has been working great. I added a new .asp page to it<BR>and then deleted it. Once I did that, I can still view and edit all of my files, but I cannot <BR>add any new files to the master web or refresh project view and synchronize files.<BR>Any tricks on how I can fix this.<BR><BR>The error is as follows ...<BR><BR>Unable to open Web project &#039;&#060;project name&#062;&#039;. An HTTP error occured. The server could not complete your request.<BR>Contact your Internet service provider or Web server administrator to make sure that the server has the FrontPage <BR>Server Extensions installed, and that the Web application exists on the server.<BR><BR>Thanks for the help. <BR>
