Your iParts fail gracefully in place, without disabling the whole page. Typically, a “problem loading” error results from some kind of bad data. By default, iMIS hides the error details:
The settings controlling this error logging reside in the <log4net> section of your site’s web.config file. The default settings enable error logging in the Windows Event log and comprehensive logging in the ASI log file, which captures both errors and warnings. This log file, Asi.WebRoot.log, is in the folder above your website root.
Contact your hosting administrator if you need access to information in these logs.
