I've developed some custom SharePoint webparts using the PI-SDK. When deployed on my test SharePoint server they work fine. However when I've attempted to install them on a different SharePoint server, they install successfully and I'm able to add said webpart to a page. However the viewing area of the webpart isn't visible (ie: there is a webpart but nothing visible). I've opened up all the security settings (atleast I think) to the .XAP and to the webpart itself.
I guess the question is. Has anybody ever run into this problem? Also, this server has RTWebParts installed where as my test server did not. Is there a possibility that the custom security used in the web.config is causing this issue?
Thanks in advanced.
