I have installed Visual Studio 2012 Express for Web and loaded an existing web site. I ran Web Developer Tools and selected Security. I got the following error message:
There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected
to a page where you can choose a new data store.
The following message may help in diagnosing the problem: Unable to connect to SQL Server database.
I have created the web site in Expression Web 4 and I have installed Members Login. I am not experienced in Visual Studio.
What is my problem and what is the solution?
