Joe,
I get a null reference exception when posting a feedback on a blog entry.
The exception orgionated from BlogView.aspx.cs, I had a look around and found I was missing 'ContentNotifyOnComment' from mp_ModuleSettings, then I had a look in mp_ModuleDefinitionSettings, it was missing there also.
I added them using an insert statement, then everything was fine.
insert into mp_ModuleDefinitionSettings(ModuleDefID, SettingName, SettingValue, ControlType, RegexValidationExpression) values (12 ',ContentNotifyOnComment', 'true', 'Checkbox', '')
This all was on a newly downloaded and installed version of mojo running on .net 2.0 with a newly created mssql database.
I think you should add the setting to mojoPortal.Business.CreateInitialData (and other places you see fit)
Also I was unable to find where the setting can be altered using the interface.
Regards,
Jelle
