I have started to get errors when posting in our forum. The error occurs when entering some specific tags which has already been used in other posts (but not all of them). When inspecting the log files on the server I can see the following error:

05/04/2017 12:48:04 | <In Memory Module> | lambda_method |  | 0 | An error occurred while updating the entries. See the inner exception for details. INNER EXCEPTION: An error occurred while updating the entries. See the inner exception for details. INNER EXCEPTION: Cannot insert duplicate key row in object 'dbo.TopicTag' with unique index 'IX_Tag_Slug'. The duplicate key value is (test).
The statement has been terminated.

 

Has anyone seen this problem?
