I recently opened our sharepoint publishing site to edit a few minor things, it was the first time mind you and i couldn't even find the default page after opening the site. Anyway after closing it I was hit by server error because Sharepoint Designer had planted little folders in the website (something like _vnf) anyway after deleting the files we managed to get back online..BUT there is an error where the webpart used to be which reads:-
'Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Windows SharePoint Services-compatible HTML editor such as Microsoft Office SharePoint Designer. If the problem persists, contact your Web server administrator'.
My questions are:-
1. How can i remedy this problem?, I'm very wary of opening Sharepoint Designer as the error suggests as it may trash the site again
2. What is the best way to modify a publishing page such as moving around place holders, webparts,etc without causing further trouble.
