Hi

I have a TFS running and tried to modify the project portal start page. But
everytime I try to add a new web part, I get the following error:

"An unexpected error has occurred.

Web Parts Maintenance Page: If you have permission, you can use this page to
temporarily disable Web Parts or remove personal settings. For more
information, contact your site administrator.

Troubleshoot issues with Windows SharePoint Services."

The interesting thing is that I can modify existing web parts (like changing
its name) and I'm also able to do things like creating new document libraries
and the like.

I should have all permissions, as I'm an administrator on the site, altough
it looks like a security issue to me.

Does anyone know how to fix this?

Alex
