Hello,

We're running v3.7 of Sitefinity. Whenever a user tries to begin the approval workflow process, they are greeted with the following error:

More than one runtime service exists of type "CmsWorkflowService".

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.InvalidOperationException: More than one runtime service exists of type "CmsWorkflowService".

We have not applied any patches. Everything was running fine until this morning. Any ideas how to fix this problem?

Thanks.

Hi Ric,

I've come across this error in the weblog unsing 3.7 sp4, stack trace below.

What I did to get around this was recopy the sitefinity folder over to the web server again and make a change to web.config so it was restarted. I can't give any further insight into why this happened or if it will happen again, however this seems to be working for the time being. Would be good if someone from Sitefinity could offer some input.

Regards
Mark

Hello Ric,

What is the build version of Sitefinity you use and the environment where the project is hosted - IIS, OS , DB server?

Mark's suggestion works.But could you please give us some more insight about why it error occurs. It occurred to me three times in last six months.
Here is the system/environment details:
OS : Windows Server 2003
IIS: 6.0
DB: SQL Server 2005 (SQL Server 8.0.818)
Sitefinity 3.7 SP4

Thank you in advance

Hello Khurshid,

The issue could appear if you use IIS6 with Windows 2003 and Sitefinity 3.7 Sp4 build for .NET 4.0. The build for .NET 4.0 requires IIS7. Please host the project under IIS7 and let me know if you still have issues.
