Error "Sequence contains no matching element" in dotnetnuke

posted on


Suddently, my website is down and get Error "http error 503. the service is unavailable."  I look up in Logs and get the message "Sequence contains no matching element" 

Searching in interner I found some thread solved this problem at here

Following these steps I solved my problem:

1. Connect SQL Server and run the query. Using generate script in SQL Server to script table Webserver. Save sript to your local drive

2.  Select * from Webserver . You will see the duplicate row

3.  Using Truncate table Webserver

4. Open the script that generated table Webserver and run it

5. Finally, Recycle your IIS
