Problem addin web part

Oct 24, 2011 at 10:46 AM

Hello everyone!
I'm using this great tool and i add and configure it in page under uno webapplication without problems.

Now an other customer ask me to configure under another webapplication the same webpart but when i add into my page it return me the following error:

"Impossible to view or import a Web Part control or module on this page. The type is not registered as safe control"

The strange thing is that my two webapplications are running under the same farm on the same server.

Somebody can help me?
