Looks like your connection string for SQL Server contains something the data layer of uCommerce isn't happy with. Specifically "flush interval". If you remove it, you'll probably be good to go.

You'll want to run the uCommerce installation one more after after the connection string is fixed to make sure the databases are set up properly.

Which version of Umbraco are you installing on? The flush stuff didn't use to be part of the default connection string so it looks like something changed and we have to look into to avoid this going forward.

ok I made a fresh installation of Umbraco setup with a SQL Server DB, the one where you login with the "sa" user (not the CE ..).

I deleted the "flush interval" part from the connectionstring, the grey part in the picture below: I then installed the uCommerce package, and now I get this error:

Have you seen this error before?

I am using Umbraco 7.3.4

Hi Rasmus,

uCommerce does not support SQL CE. You need as minimum a SQL server express to run.

I ran through the regular set of installation tests for Umbraco 7.4.1 we have. SQL and Azure options will not add the "Flush Interval" option to the connection string, only SQL CE will do this.

What might have happened is that SQL CE was used to the first set up and later changed to point to full SQL Server leaving the flush interval option in the connection string.

If this is the case your best course of action is to change the connection string to not include "Flush Interval".

Should the site still be running on SQL CE, please make sure that you complete the move to SQL Server before proceed.

hmm ok thats weird .. this site has never been running on SQL CE ..

I tried to uninstall Webmatrix and installed it again, then I made a new Umbraco site running on SQL Server Express logging in with the "sa" user, but the connectionstring still has the "Flush Interval" part .. I Deleted this part from the connectionstring and installed the uCommerce package but with the same outcome as last time, I got the "A network-related or instance-specific error ...." again as the one I posted a screendump of ..

So I still got this YSOD .. any other ideers?

ok I really dont get it, looks like the connectionstring is actually pointing at a SQL CE server even though i set it up to the ordinary SQL Server Express using Webmatrix .. this is how the full connectionstring looks like (after i deleted the "Flush Interval" part ..): I guess the providername is telling that it is pointing to a SQL CE server?

But it has also made some databases in the SQL Server Express I can see in Microsoft SQL Server Management Studio .. :

Could these informations help me to a solution?

Manually change the connection string in the web config

<add name="umbracoDbDSN" connectionString="Server=localhost\SQLEXPRESS;Database=YOURDB;user id=sa;password=YOURPWD" providerName="System.Data.SqlClient" />

Ok i managed to get it to work on a clean Umbraco version 7.0.2 without using Webmatrix ..... for now :)

Thank you for your effort to help me out, very much apriciated, I guess there will be comming other problems that hopefully will be more specific .. But thanks for now :)
