I am running DNN 4.8.3 with Events moduel on a calendar page set to calendar view. I have events module on home page linked to subcalendar which is set to list view only. When I first view the site the event list module shows an error in the module. If I goto calendar page then back to main page the event list shows properly. I am new new DNN. Have I linked the calendars incorrectly or is this a bug. The following is the error displayed in event viewer.

I was about to start a new post, when I saw that this describes my problem exactly. My Events module is 03.03.08, DNN 04.08.02, hosting service is MyHosting.com. I have screen shots if it helps.

Yes, and it seems to work. The problem could be recreated if I quit Safari and returned to the site, and I also retested after rebooting a PC. Sorry I didn't see the workaround to begin with, but I'm glad the dev team has a fix.
