Deleted Default Notification Profile - Null Reference Except

Hi,

 I accidentally deleted the default profile for the email notifications module via Sitefinity Administration Settings.

 I am now unable to load my application. I keep getting the following error when Sitefinity loads up.

 Can you offer any advice on how I may repair this?

The error is as follows:

Server Error in '/' Application.Object reference not set to an instance of an object.Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I'm using Sitefinity 6.3.5.

Many thanks,

Hello Rob,

Thank you for using Sitefinity.

Please open the notifications config file under:
~\<your project>\App_Data\Sitefinity\Configuration\NotificationsConfig.config

Thank you very much Svetoslav.

 You solution worked perfectly.

 Really appreciate it.

Rob

I had my workflow email notifications working just fine. Now they do not after some modifications. I have my Systems > SMTP settings and Notifications > Profile set up.

I noticed after this post that a NotificationsConfig.config file does not exist in my project. Is this normal? Where can I get a default one if mine disappeared?

Hello Tom,

Please try the solution proposed in the second part of my previous post: - Create a new NotificationsConfig.config under  ~\<your project>\App_Data\Sitefinity\Configuration\ and use the default content provided.

Than configure the notification settings once again.

Regards,
