I get the same error. I try it also as sa_sps and get the same error. The web part that we are attempting to delete is an imagewebpart that no longer responds to attempts to edit the web part. The message just confirms that somehow things are corrupted. What are some of the options to resolving a problem like this? Thank you! Server Error in '/' Application.

Hello, Open the site in SharePoint Designer and for the webpart whic is causing the problem, remove the WebpartID along with the GUID. Once this is removed, save the page (after which the GUID will be regenerated). Try accessing the page now. Let me know if this works. Thanks, DipDip http://dzeee.net/sharepoint

I wasn't certain how to remove the GUID. What I found I had to do was go into a higher level site above the place where the problem was occurring, then click my way down the folder structure until I found the default.aspx. I highlighted the web part that was corrupted and deleted it. I saved the page, which asked if I was sure I wanted to create a new default.aspx page. I indicated "sure!" and that worked out. So, perhaps SPD deleted the two parts in question.

No, I have seen that page in the past, but in this case, it was not a content view web part, but an image web part. The web part would not allow us to edit it to see what was inside, so I just went the route of opening the site in sharepoint designer and deleting the web part.
