I've got a custom webpart that's working great on different MOSS-servers. Now I tried to use this webpart on a 2nd sitecollection (B) on a server. It's already running on sitecollection A. What I did: The wsp-file is present on the server, so I just used: %STSADM% -o deploysolution -n xyz.wsp -local -url http://localhost:12345 in the servers console. I activated the webpart's feature and so on. When I try to add it to a site I get so following message:
A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe.
I also tried to change the webconfig of the 2nd site collection to trustlevel:Full, but nothin changed. Rebooting IIS and the server itself didn't help, too.
Can anybody help me?
Thanks in advance
