Roles are not working
===

I've manually published my asp.net website via ftp everything works fine( login,register etc..)
But roles are not working , for example : a page made only for admins can be accessed by normal users.

Here's my web.config:

    <?xml version="1.0"?>
    <configuration>
      <connectionStrings>
        <add name="MyConnStrg" connectionString="provider details..etc.."
          providerName="System.Data.SqlClient" />
      </connectionStrings>
        <system.web>
          <roleManager enabled="true" defaultProvider="MyWebsiteTC">
            <providers>
              <add name="MyWebsiteTC"
              type="System.Web.Security.SqlRoleProvider"
              applicationName="/"
              connectionStringName="MyConnStrg" />
            </providers>
          </roleManager>
          <membership defaultProvider="MyWebsiteTCMembershipProvider">
            <providers>
              <add name="MyWebsiteTCMembershipProvider"
              type="System.Web.Security.SqlMembershipProvider"
              connectionStringName="MyConnStrg"
              enablePasswordRetrieval="false"
              enablePasswordReset="true"
              requiresQuestionAndAnswer="true"
              applicationName="/"
              requiresUniqueEmail="true"
              passwordFormat="Hashed"
              maxInvalidPasswordAttempts="5"
              minRequiredPasswordLength="7"
              minRequiredNonalphanumericCharacters="1"
              passwordAttemptWindow="10"
              passwordStrengthRegularExpression=""/>
            </providers>
          </membership>
    
          <compilation debug="true" targetFramework="4.0" />
          <authentication mode="Forms">
            <forms name=".KKDS"
              timeout="30"
              slidingExpiration="true"
              cookieless="UseCookies"
              defaultUrl="~/Default.aspx"
           />
          </authentication>
        </system.web>
    </configuration>

Admin files are in a folder with this web.config:

    <?xml version="1.0"?>
    <configuration>
      <system.web>
        <customErrors mode="Off"/>
        <authorization>
          <allow roles="Client" />
          <deny users="?"/>
        </authorization>
    
      </system.web>
    </configuration>

Roles were added for each user everything works fine but not the roles auth.
What can I do?
