If you may get an error same as below on image,



You need to check your database connection string in web.conf file

I have forgot to add parameter  providerName="System.Data.SqlClient" on connectionString



<connectionStrings>

    <add name="PR" connectionString="server=50.28.66.8;database=Rakesh2010_GlobalEducation;uid=RSakti_2010;pwd=rakesh2010;pooling=false" />

  </connectionStrings>


Change to below format,


<connectionStrings>

    <add name="PR" connectionString="server=50.28.66.8;database=Rakesh2010_GlobalEducation;uid=RSakti_2010;pwd=rakesh2010;pooling=false" />

  </connectionStrings>


Once you have updated the web.config file save it.
