Hi Sebastian

I tried to install the module again from the DNN 4.3.5 installation file, and from a new download, both under full and medium trust. Made no difference.

I then examined 03.01.00.sqldataprovider and 03.03.00.sqldataprovider.

Both files have the same code to create the same stored procedures (in name anyway, code inside procedure may/may not be different), however 03.03.00.sqldataprovider is missing:

create procedure {databaseOwner}{objectQualifier}DeleteLink

@ItemId int

as

delete
from {objectQualifier}Links
where  ItemId = @ItemId

GO

So the problem is one or both of the below perhaps?

a) When installing the module in DNN 4.3.5 the 03.01.00.SqlDataProvider does not get executed.
b) The code above is missing from the 03.03.00.SqlDataProvider script.

Do you think it's a, b or both? Should I log this in Gemini as a bug?

Either way your solution worked of course!

Many Thanks!

Alex
