Hi,

I am getting this error message on an old client's website.  Its happening everything pretty much every second now.  DNN version 05.02.00 (275)

When I go into schedule and try and edit a schedule I get this error message
Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.Admin.Scheduler.EditSchedule.BindData() at DotNetNuke.Modules.Admin.Scheduler.EditSchedule.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

Any ideas?
Thanks

Thanks for your quick feedback.  When I go into the schedule under host  I see a list of 12 jobs that have no name and frequency is set to n/a.

i clicked on schedule status and it says the following:
There are no tasks in the queue and no tasks are processing.

Current Status:	RUNNING_REQUEST_SCHEDULE
Max Threads:	1
Active Threads:	0
Free Treads:	1
Command:	Start    Stop

When I look at schedule history the last time something run was 2/8/2010.

So not sure what is happening.  It seems that General exceptions only start when I log in as host.  When I log in as Admin I do not see the General Exceptions.

Thanks
Ginnie
