I have deployed a webpart to my MOSS 2007 environment and have the following error:
"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."
The strange part of this is, that the sharepoint site sits on 2 front end web servers that are load balanced, one of the web servers displays the webpart fine, and the other one gives the error.
web.config on both servers is the same, the .dll for the webpart is on both web servers in the appropriate bin directory and with the same permissions.
also to note, the webpart was deployed on the central admin server which is a separate server to both web servers.
the event log doesn't display anything to give any hints as to why this is failing, how can I troubleshoot it?/resolve it?
